ChuckandClaude Opus 5 efc7856294 Merge origin/main (#592, #593, #594) into the September 16 core audit fixes
config.py conflict: #594 discovers plugins before /config/main matches plugin
keys; this branch routes those sections through the /plugins/config
preparation (F13). Kept both.

#594's secret-separation test posts a plugin section to /config/main, which
this branch now validates through api_v3.schema_manager; the test gets a real
SchemaManager over its temporary plugins directory instead of the helper's
mock. It still fails if the discovery call is reverted.

ChuckandClaude Opus 5 f475038895 fix(cache): web UI can read what the display service caches again (#593)
* fix(cache): web UI can read what the display service caches again

ledmatrix-web.service carried CacheDirectory=ledmatrix. With User= set to
the installing user, systemd re-owns /var/cache/ledmatrix and everything
in it to that user and its primary group whenever the directory's owner
differs -- for a directory root created, on the first start. That erased
the root:ledmatrix setgid layout the installers set up, so every file the
display service (root) wrote afterwards was root:root 0660 and unreadable
by the web interface:

  WARNING - Permission denied loading cache for display_current_state ...

Since #547 install_service.sh renders the web unit from the template, so
every fresh install hit this. Measured on one rig: 392 unreadable files,
and the web UI's display status, on-demand state and plugin health empty.

Existing installs only receive `git pull`, never a reinstalled unit, so
the fix for them is in the code the root display service runs:

- DiskCache.set gives each file the directory's group (when the directory
  is group-writable) and 0660 on the open descriptor before the rename,
  independent of setgid. This also closes a window where a fresh file was
  visible as mkstemp's 0600.
- DiskCache.share_existing_files repairs files an older version left
  behind, once per process from the cleanup thread. It works through
  O_NOFOLLOW descriptors and skips hard links and other users' files: the
  directory is writable by the web user, and root must not be steered
  into changing a file outside it.

For new installs, the web unit drops CacheDirectory=/CacheDirectoryMode=,
and install_web_service.sh stops replacing an existing directory's
ledmatrix group with the user's group.

* fix(web): on-demand and current-display status read the display's latest state

Found testing the cache-permission fix on a rig: once the web interface
could read display_on_demand_state at all, /display/on-demand/status kept
answering "active" for over 100 seconds while the file on disk said
"idle". Both status routes read the display service's keys through the
web process's memory tier, which serves the first copy it read for the
full max_age (120s). Read them with memory_ttl=0, as every other
cross-process reader (plugin health/metrics, the on-demand mailbox)
already does.

* fix(install): re-group the cache dir whenever the web user is outside its group

install_web_service.sh replaced an existing cache directory's group only
when it was root's. A directory in any other group the web user is not a
member of -- root:ledmatrix, for a user who is not in ledmatrix -- was left
alone, and every file root wrote there stayed unreadable to the web
interface. Replace the group whenever the installing user is not in it.

A directory whose group the user is already in (ledmatrix, or the user's
own group where CacheDirectory= left it) is still left as it is: re-grouping
a working directory strands the files already in it on the old group.

When the group does change and root-owned JSON files carrying the old group
are present, try-restart ledmatrix.service so DiskCache.share_existing_files
re-groups them through its symlink- and hard-link-safe path, rather than a
recursive chgrp.

Verified under WSL's systemd for seven directory states (user group,
ledmatrix member, ledmatrix non-member with and without root files,
root:root, missing, unnamed gid); the previous version left the non-member
case unchanged.

Addresses CodeRabbit review on #593.

ChuckandClaude Opus 5 1d51efe4c7 fix(backup): restore over existing files on hosts without os.chown (#592)
_copy_file() replaces each restored file and then carries the previous
owner across with os.chown. On Windows os.chown does not exist and
st_uid/st_gid are 0 rather than absent, so the ownership branch always
ran and raised AttributeError. That is not an OSError, so it escaped
every per-section handler in restore_backup(): a restore over any
existing config aborted at config.json and restored nothing.

Skip the ownership step where os.chown is missing, as
auto_update_setup.py already does. No change on POSIX.

test_restore_over_a_file_the_user_cannot_write simulates root-owned
files with chmod 0o444; on Windows that sets the read-only attribute,
which blocks any rename over the file, so it is skipped there. The
modes the app writes (0o644/0o640/0o600) replace fine on Windows.

ChuckandClaude Opus 5 d284fdeb46 fix(plugins): prepare plugin configs one way for load, saves, GET, hot reload and dev tools
Plugin config was prepared differently depending on how it arrived:

- JSON POST /plugins/config built a partial body on schema defaults, so
  {"enabled": true} reset every other setting of the plugin. It now merges
  onto the stored section first, as the form path already did.
- Legacy-boolean normalization (#588) ran only at load: GET /plugins/config
  returned the raw boolean, posting it back failed validation, and hot
  reload handed plugins the raw section (a legacy dynamic_duration: true
  came back as a boolean). schema_manager.prepare_plugin_config (normalize,
  then defaults) is now used by PluginManager.load_plugin, both save paths,
  GET, the save notifications and DisplayController's hot-reload callback.
- The JSON save's filter kept only enabled/display_duration/live_priority
  and dropped a submitted skin, skin_options or vegas_* tuning key. There
  is now one core-owned per-plugin list, schema_manager.CORE_PLUGIN_PROPERTIES,
  used by validation and by the save filter; PluginManager's
  CORE_OWNED_CONFIG_KEYS is its vegas subset.
- Plugin sections posted to /config/main were stored verbatim, including
  values /plugins/config rejects. They now go through the same preparation
  (_prepare_plugin_config_for_save, extracted from save_plugin_config), and
  a failing section rejects the whole save before anything is written.
- dev_server read only top-level defaults and let a schema enabled:false
  win; build_full_config shallow-merged overrides, dropping sibling
  defaults; the harness extracted defaults differently from the device.
  loading.build_config now uses the device's extraction and preparation,
  and dev_server, check_plugin, render_plugin and the harness all use it.

ChuckandClaude Opus 5 b2d9b91a66 fix(update): keep the rollback's pip retries inside the unit time limit
The health check reinstalled the previous requirements by trying the
next bash path after any failure, including a 600 s pip timeout. Two
files, two paths: up to 40 minutes of pip alone, while systemd stops
ledmatrix-update-verify.service at TimeoutStartSec=30min -- killing the
rollback half-way and leaving the update 'verifying' until the web UI
calls it lost.

- Like permission_utils.install_requirements_file, only a sudo refusal
  moves on to the next bash; a pip that ran and failed or timed out is
  not repeated. The refusal wording is one list
  (permission_utils.SUDO_REFUSAL_PHRASES), mirrored in the stdlib-only
  verifier and pinned equal by a test.
- All reinstalls in one rollback share a 600 s budget.
- WORST_CASE_SECONDS adds up every timeout on the longest path (27.5
  min); a test holds it under the unit's TimeoutStartSec and that under
  the web UI's VERIFY_LOST_SECONDS.

ChuckandClaude Opus 5 f867fafa08 fix(scripts): scroll_speeds.py opens the panel with the service's options
--measure and --demo built RGBMatrixOptions from a private copy of the
display service's builder that had drifted: gpio_slowdown came from
display.hardware (default 2) instead of display.runtime (default 3), and
rp1_rio, panel_type, disable_hardware_pulsing, inverse_colors,
pixel_mapper_config and orientation were skipped, with different defaults
(hardware_mapping "regular", pwm_bits 11). A panel needing a high slowdown
was measured -- or garbled -- in a setup the service never drives.

The option filling in DisplayManager._setup_matrix moves, unchanged, into
DisplayManager.apply_matrix_options(options, config), which _setup_matrix
calls and the script reuses (overriding only limit_refresh_rate_hz for
--measure). The script now loads the whole config rather than the hardware
block. Tests pin the script's options to the service's attribute for
attribute.

ChuckandClaude Opus 5 94ec74caa5 fix(display): refuse settings the rgbmatrix library aborts on, on every board
The library answers several settings with a NULL matrix or abort() rather
than an error, so the display service crash-looped (Restart=on-failure)
instead of reaching fallback mode: rows above 64, chain_length above 255
(uint8_t binding setter, documented as "no upper limit"), a misspelled
hardware_mapping, and parallel 2-3 on a single-output mapping, reachable
from the Display form on the default adafruit-hat(-pwm) mapping. #586 only
guarded the Pi 5 subset.

- src/matrix_support.py holds the rules for every board (Options::Validate
  ranges, binding integer types, mapping names and outputs from
  lib/hardware-mapping.c) plus the Pi 5 ones, and is the one source of the
  API's numeric ranges.
- DisplayManager checks them before building options and raises
  MatrixSettingsRefused, so a hand-edited config falls back with a logged,
  reported reason. Emulator mode only warns.
- The config API refuses them with a 400 naming the setting; combinations
  are checked against stored values but reported only when the request
  sets a field involved.
- The hardware status file gains "cause" (settings/library/forced). The
  fallback log and Display banner give the Pi 5 rebuild hint only for a
  library failure instead of rebuild + gpio_slowdown advice for every
  failure; one Pi 5 slowdown recommendation (1-3, start at 1).
- The Display form offers classic/classic-pi1 and orientation 90/270 and
  renders any other stored mapping selected with a warning, so an
  unrelated save no longer rewrites them; the API accepts 90/270.

ChuckandClaude Opus 5 c693278d33 fix(display): size the preview after orientation and pixel mappers
display_geometry.physical_size claimed to give DisplayManager's answer but
only computed cols*chain x rows*parallel. RGBMatrix.width/height are measured
after the library's pixel mappers, so a Rotate:90 / orientation 90 chain
previewed 128x32 for a 32x128 panel and a U-mapper chain of four 256x32 for
128x64.

Model the built-in mappers' size effect as the pinned lib/pixel-mapper.cc
does (Rotate, U-mapper, V-mapper, StackToRow, Remap; Mirror and unknown
names leave it alone), and move the orientation composition here so
DisplayManager and the preview share it. The module docstring no longer
claims the sync handshake uses it; that imports only DEFAULT_CHAIN_LENGTH.

Audit finding F18.

ChuckandClaude Opus 5 33c1bbe8d9 docs(config): mark target_fps legacy; describe what Vegas scroll_delay does
- General tab "Scroll Frame Rate" (target_fps) is labelled legacy: after
  the sports_scroll fix nothing in core scrolling reads it. The field and
  its API validation stay so saved configs and plugins that read
  global_config['target_fps'] keep working. CONFIG_REFERENCE says the same.
- Vegas frame_based_scrolling/scroll_delay were described as frame-count
  stepping at ~50 FPS. Neither steps nor sets a frame rate: frame-based
  mode converts the speed to px per scroll_delay, clamps it to 0.1-5, and
  still advances by elapsed time, so the applied speed is
  clamp(scroll_speed * scroll_delay, 0.1, 5) / scroll_delay px/s. The
  config comments, render_pipeline comment and CONFIG_REFERENCE rows now
  say so. No behaviour change.

ChuckandClaude Opus 5 ec57b35448 docs(scroll): describe the fixed-step model and document frame_hold
Since #545 a crisp speed from scroll_config.configure() makes the helper
advance a fixed whole-pixel step per presented frame with no clock, and the
display manager's frame hold is part of the speed. The docs still described
the removed wall-clock model:

- scroll_config's module and configure() docstrings said speed is applied
  in time-based mode and that omitting the hold "falls back to fractional
  pixels"; omitting it actually runs the scroll frame_hold times too fast.
- SCROLL_PERFORMANCE.md said ScrollHelper accumulates elapsed time in both
  modes, and read a 20 ms stats median as missed refreshes although that
  is a healthy 50 px/s (hold 2) scroll. It now explains the fixed step,
  the hold-dependent healthy median, that target_fps plays no part, and
  that a hand-added scroll_pixels_per_second loses to a schema-default pair.
- PLUGIN_API_REFERENCE.md documented set_scrolling_state(is_scrolling)
  without frame_hold; it now documents the parameter (core 3.4.0) with a
  configure() + set_scrolling_state example.
- update_scroll_position/set_scroll_speed and set_scrolling_state
  docstrings say the same.

ChuckandClaude Opus 5 df3524305f docs(plugins): one display-size contract: display_manager.width/height
CLAUDE.md (#580) says to read display_manager.width/height because
matrix is None when hardware init fails; the development guide, the
safety-harness doc and two DisplayManager docstrings still recommended
matrix.width/height. The bundled starlark-apps plugin read matrix.width
unguarded, so its magnify recommendation and frame scaling raised in
fallback mode (e.g. after the Pi 5 hardware refusal).

StartupValidator warned "Plugin 'auto_update' is enabled but not found" on
every display start with auto-update or a dim schedule on; the reserved
plugin-id check missed auto_update, sync, location and the rest; and
ConfigManager's (uncalled) orphan cleanup would have deleted display,
schedule and auto_update. All three now read src/core_config_keys.py, which
also gains CORE_SECRETS_KEYS for the github/youtube secrets sections.

ChuckandClaude Opus 5 e62ec164f8 refactor(scroll): remove dead code left by #523/#570
- Drop the optional scipy.ndimage import and HAS_SCIPY; nothing read
  them since the numpy blend replaced the scipy path.
- Drop ScrollHelper._last_integer_position and frame_time_target, which
  were written but never read.
- Keep target_fps and set_target_fps() but document them as
  informational: nothing paces off them, yet ledmatrix-elections'
  test_scroll_pacing.py reads helper.target_fps back and third-party
  plugins may call the setter.
- Fix stale comments: fixed_pixels_per_frame's "use scroll_delay to
  throttle", set_sub_pixel_scrolling's "default: True", and
  set_frame_based_scrolling's claim that it steps.

The plugins monorepo was grepped for every removed name; none is used.

ChuckandClaude Opus 5 1ad8275ab5 fix(scroll): restart the stats window when an idle gap is dropped by size
#582 dropped an idle gap from the frame stats two ways: the reset_scroll()
sentinel, which also restarts the 5s window timer, and a size guard for
scrollers that never call reset_scroll(), which did not. On that path the
first real frame after the gap found the boundary overdue and logged a
stats line for a one-frame window. Both paths now share one seeding helper.

ChuckandClaude Opus 5 4564dc172d fix(sports): scoreboard scroll speed no longer follows target_fps
sports_scroll computed the crisp speed ladder against the global
target_fps whenever limit_refresh_rate_hz was the 100 Hz default. Since
frame-locked presentation (#545) the helper steps a fixed number of whole
pixels per presented frame and the panel presents at its real refresh, so
the General tab's "Scroll Frame Rate" became a speed multiplier: 60 ran a
50 px/s scoreboard at 100 px/s, 200 ran it at 25 px/s.

The ladder now uses the display manager's refresh_hz, then
display.hardware.limit_refresh_rate_hz, then the default. target_fps is
not consulted. Docstrings now say scroll_delay is ignored for pacing (no
behaviour change there) and describe the fixed-step model.

Tests: replace the tests that pinned target_fps as the ladder refresh and
described time-based stepping; assert speed independence from target_fps
(unit and end-to-end presented px/s against the real helper), that the
fixed per-frame step is applied, and that scroll_delay does not change
speed.

ChuckandClaude Opus 5 15cc6926a4 fix(web): keep plugin asset and action routes inside their directories
POST /plugins/assets/upload, GET /plugins/assets/list and POST
/plugins/assets/delete joined the request's plugin_id onto assets/plugins
unchecked, so '../../config' created, wrote, listed and deleted outside
it. #561 guarded only the route that serves the files. All three now go
through path_safety.resolve_under and answer 400 for anything but a
plain name, and delete only unlinks a metadata path that resolves into
that plugin's uploads directory.

PluginManager.get_plugin_directory refuses ids that are not one plain
path segment, so /plugins/action (which runs a manifest script from the
returned directory) and every other caller get the guard; the action
route also rejects such ids up front, covering its no-manager fallback.

ChuckandClaude Opus 5 837dd1fde7 fix(sports): share the ESPN rejected-range memo with the background service
BackgroundDataService always sent a season range first and, on a 400,
fell back to chunks without recording the rejection, so every background
season fetch spent a doomed request and live scoreboards learned nothing
from it (or it from them). The worker now consults and sets the same
6-hour memo fetch_espn_scoreboard() uses: a known rejection goes straight
to month/day chunks, and if every chunk fails the range is asked once for
a real error without re-spending the chunks.

ChuckandClaude Opus 5 7ae614aa35 fix(sports): recover from ESPN rejecting scoreboard date ranges (#591)
* fix(sports): recover from ESPN rejecting scoreboard date ranges

Since 2026-09-15 ESPN's site API answers `dates=YYYYMMDD-YYYYMMDD` with
400 "Failed to get events endpoint." for every sport. Single days, months
(`YYYYMM`) and season years still work. Every season and weeks-window fetch
in core failed, including the background service the scoreboards submit
their season schedules to.

src/common/espn_dates.py re-asks a rejected range as whole-month chunks
plus the leftover edge days, which tile the window exactly (a season is
8 requests, not 213). A month that comes back with exactly 500 events is
truncated (college baseball's March) and is re-asked day by day.

It also clamps `limit` to 500: above that ESPN truncates silently, e.g.
college football returns 25 of 68 games for one Saturday at limit=1000.

BackgroundDataService recovers rejected ranges on the worker thread and
advertises `handles_espn_date_ranges` so plugins can tell whether to hand
it a range. SportsCore, sports_shared, ESPNDataSource and APIHelper route
through the helper or the clamped limit.

* docs(changelog): ESPN date-range fallback and limit clamp

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(sports): stop re-sending ESPN date ranges once one is rejected

Live scoreboards refresh every 30 seconds, and each refresh sent the range
first, got the 400, then fetched the chunks: three requests where one used
to do. After a rejection, ranges now go straight to chunks for six hours,
then the range is tried again so the workaround retires itself if ESPN
reverts. A single-day 400 does not set the memo, and when every chunk fails
the range request supplies the error without the chunks being fetched a
second time. Per-fetch chunk logging drops to debug; the rejection itself
stays a warning.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(sports): clamp limit only on ESPN scoreboard submissions

The background service is generic, and limit above 500 only truncates
scoreboards. /teams needs limit=1000 (college football has 762 teams and
limit=500 returns 500), so a teams submission must keep its limit.

ChuckandClaude Opus 5 2082665252 fix(config): load config_secrets.json on hosts without os.geteuid (#590)
ensure_shared_group_ownership() - the chgrp self-heal ConfigManager runs
before reading config_secrets.json (#416) - looked up os.geteuid
unguarded. That name does not exist on Windows, and the AttributeError
is not an OSError, so it escaped the helper's best-effort handling and
every except clause in load_config(). Any Windows checkout with a
config/config_secrets.json got a ConfigError from every config load and
could not import web_interface.app.

That is what made test_update_all_plugins.py error at setup: its client
fixture imports web_interface.app. It was not state leaked between test
files - the trigger is whether the checkout has a secrets file.

ChuckandClaude Opus 5 f9b3d6ae52 fix(web): accept every panel size and row address type the rgbmatrix library does (#586)
* fix(web): accept every panel size and row address type the rgbmatrix library does

The Display form capped columns at 128 and chain length at 24, and its
submit handler (fixInvalidNumberInputs) rewrote anything larger to the cap,
so wide panels and long chains silently saved as the wrong size. The config
API checked none of the hardware numbers, so values the library rejects (odd
rows, parallel 4, PWM dither bits 3) saved and the matrix then refused to
start.

- Form limits now match the pinned library: rows even 8-64, cols >= 16 and
  chain_length >= 1 with no upper bound, parallel 1-3, PWM dither bits 0-2,
  PWM LSB nanoseconds 50-3000.
- save_main_config rejects out-of-range rows, cols, chain_length, parallel,
  brightness, scan_mode, pwm_bits, pwm_dither_bits, pwm_lsb_nanoseconds and
  gpio_slowdown with a 400.
- A stored gpio_slowdown or pwm_dither_bits of 0 renders as 0 instead of the
  default, so saving the tab no longer overwrites it.
- Row Address Type offers 5 (SM5368 / B707 row shift register). Verified on a
  Waveshare 96x48 V2 (24S-A1) on a Pi 4 with the Adafruit Triple LED Matrix
  Bonnet: rows 48, cols 96, row address type 5, BGR, GPIO slowdown 8.
- Help text and docs: FM6124-family panels use Panel Type Standard; on a Pi 5
  the library supports only row address types 0 and 2.

No change to the rpi-rgb-led-matrix submodule.

* fix(web): drop the rows cap and document every display setting accurately

Rows: no upper limit in the form or the API. Still even and at least 8. The
current rgbmatrix library rejects more than 64 per panel, so a larger value
saves but the matrix won't start; the help tip, README, config reference and
troubleshooting section all say so, and nothing here needs changing if the
library lifts the limit.

limit_refresh_rate_hz: the form accepts 0 (the library's "no cap"), a stored
0 no longer renders and re-saves as 120, and the API rejects negatives.

pwm_dither_bits stays 0-2: the library rejects 3 and 4, so the old form's
0-4 only ever let users save a config the display couldn't start with.

Docs and help tips, checked against the pinned library and its README:
- panel_type and rp1_rio get README entries
- show_refresh_rate prints to stdout; it never drew on the panel

* fix(web): reject true and 5.5 for row_address_type and multiplexing

Both still went straight through int(), so a JSON true saved as 1 and 5.5
as 5. They now use the shared hardware range check like the other panel
fields. Review feedback on #586.

Also: the RP1 Backend tooltip said it is ignored on Pi 3/4 (it is ignored
on every model but the Pi 5), and the README gave the dynamic-duration
default cap as 90s; the code default is 180s.

* feat: refuse matrix settings a Raspberry Pi 5 can't drive

On a Pi 5 the pinned rgbmatrix library drives the panel through the RP1
chip, and that path supports only row address types 0 and 2, parallel 1-3
and the regular / regular-pi1 / classic / adafruit-hat(-pwm) mappings
(Rp1PioConfigSupported in lib/rp1/rp1_pio_backend.cc). For anything else
CreateFromOptions returns NULL; the Python binding doesn't check, so the
display process crashed on its first call into the matrix and systemd
restarted it into the same crash every 10 seconds.

- src/pi5_matrix_support.py: the rule and Pi 5 detection, matching the
  library's /proc/device-tree/model check
- DisplayManager raises before creating the matrix, so it is a logged init
  failure (reported by /api/v3/hardware/status) and fallback mode
- the config API rejects those settings on a Pi 5 when a request sets
  row_address_type, parallel or hardware_mapping
- the Display form offers only row address types 0 and 2 on a Pi 5, and
  warns when a stored value can't be used
- CLAUDE.md: re-check the rule whenever the submodule is bumped

Review feedback on #586.

ChuckandClaude Opus 5 9616a5a054 fix(web): auto_update and other core settings are not orphaned plugins (#589)
v3.4.0 shows "Plugin Config Warning - In config but not installed:
auto_update. Reinstall via the Plugin Store, or remove these entries from
config.json." auto_update is the core weekly-update setting from #581.
Reconciliation treated every top-level dict not in its private
_SYSTEM_CONFIG_KEYS list as a plugin id, and #581 could not know to extend
that list.

- Move core top-level keys into src/core_config_keys.py (CORE_CONFIG_KEYS)
  and use it in reconciliation. Tests fail if a config.template.json key or
  a key written by the general-settings save is missing from it.
- A secrets-file key only counts as a non-plugin when no installed plugin
  has that id. Plugin secrets are namespaced by id, so installed plugins
  with secrets were reported as missing from config on every run.
- still_unresolved() drops "not on disk" findings whose id is no longer a
  plugin entry in config, so a stored verdict clears without a restart.
- A plugin whose id is a core key is skipped with a warning, and the fix
  never writes a plugin stub over or in place of a core setting.

ChuckandClaude Opus 5 c200b5837d fix(plugins): normalize legacy boolean settings before schema validation (#588)
The news plugin's schema turned global.dynamic_duration from a boolean
into an {enabled, min_duration_seconds, ...} object. Installs that have
not saved the news settings since still hold `true`, so every start
logged "Plugin news config does not match its schema (loading anyway):
Field 'global.dynamic_duration': Expected type object, got bool" and
flagged news degraded.

The settings form already reads such a boolean as {"enabled": <bool>}
(render_nested_section in plugin_config.html) and the next save writes
the object. The loader did not. It now applies the same rule before
merging schema defaults and validating, so the defaults fill in the rest
of the object and the plugin receives it in the new shape.

The rule lives in schema_manager.legacy_bool_as_object /
normalize_legacy_booleans. It applies at any depth of nested objects
but not inside arrays, matching the form, and only to a real bool under
an object-typed property with an `enabled` child. Every other mismatch
still warns. A parity test renders the template macro against the helper
so the two cannot drift.

Nothing is written to config.json at load: the normalization is in
memory, and the next save of the plugin's settings persists the object.

ChuckandClaude Opus 5 8360220809 feat(common): sports_helpers — the helpers all nine scoreboards carry identical copies of (#583)
* feat(common): sports_helpers, the helpers all nine scoreboards copy verbatim

Add src/common/sports_helpers.py: the helpers the scoreboard plugins'
sports.py carry byte-identical copies of (docstring-stripped AST, checked at
ledmatrix-plugins f09bff2), so a later plugins PR can delete its copies once
it floors on the core release that ships this.

- Free functions: clamp_window, clamp_seconds, logo_needs_refresh (lazy
  src.logo_downloader import, as in the plugins), spread_weighted_order,
  MIN_WINDOW_DAYS / MAX_WINDOW_DAYS. All nine plugins.
- SportsHelpersMixin (no __init__, stateless): _mode_customization,
  _setting_int, _reset_dwell_on_reentry, _next_switch_index,
  _spread_weighted_order (all nine), _odds_color and
  _upcoming_date_and_time_text (all but ufc), plus the _favorite_key seam
  from base_classes core.py for later phases.

A new module rather than more methods on sports_shared: a plugin that
deletes a copy and relies on an existing module having grown the method
fails at runtime with AttributeError on an older core, which neither the
loader nor check_min_core_version.py can see; a missing module fails at load.

Tests: behaviour for every helper, a derived host contract, and a parity
test that AST-compares every body against every plugin copy when
LEDMATRIX_PLUGINS points at a checkout (skipped otherwise).
test_common_is_hardware_free.py imports src.common and every sports_* module
with rgbmatrix blocked and scans src/common for module-level imports of
src.base_classes, src.display_manager and src.plugin_system (no existing
violations).

Nothing in core imports the new module; no behaviour change. CHANGELOG
Unreleased entry and a converging note in docs/SPORTS_UNIFICATION.md.
__version__ is not bumped.

* fix(common): address review on sports_helpers and the hardware-free test

- SportsHelpersMixin docstring and CHANGELOG: constructor-free, but it keeps
  lazy state on its host (_reset_dwell_on_reentry, _next_switch_index).
- test_common_is_hardware_free: the runtime check now filters every
  FORBIDDEN package, src.plugin_system included; the AST scan resolves
  relative imports against src.common, so `from .. import plugin_system`
  and `from ..plugin_system import x` are caught. Guard tests for both.
- Parity skip reason names the CI guard that runs the same comparison:
  ledmatrix-plugins scripts/check_sports_helpers_parity.py (#495).
- _odds_color: line-level pylint disable for a not-callable false positive
  (getter is None-checked); the AST is unchanged, parity still passes.

ChuckandClaude Opus 5 869e36fb2f feat(web): weekly automatic updates with health check and rollback (#581)
* feat(web): weekly automatic updates with health check and rollback

A General-tab toggle (off by default) checks for and installs LEDMatrix and
plugin updates once a week, overnight in the configured timezone.

- Pre-update checks skip (and report) instead of forcing: local edits or
  commits, merge/live rebase, no upstream, low disk, missing health check, or
  a version that was already rolled back. An abandoned rebase (HEAD back on a
  branch) is cleared, since it would otherwise block every pull.
- The pull reuses the Update Code path (now perform_core_update(), which
  reports dependency install failures as data).
- ledmatrix-update-verify.service, started via a .path unit from a request
  file, restarts the services from its own cgroup, requires them to come up
  and stay up, and otherwise resets to the previous commit and reinstalls the
  previous requirements. It runs a copy of the checker taken before the pull.
- No SSH needed: switching the toggle on restarts the display service, which
  (as root) installs the two units from the repo templates for the web user.
  first_time_install.sh installs them too and takes --enable-auto-update /
  LEDMATRIX_AUTO_UPDATE (passed through by one-shot-install.sh).
- Plugins update after the code passes its check; failures, blocks and
  rollbacks raise an Overview banner and show under the toggle.

Tested end to end on a Pi: web-UI setup, a good update, a broken web service
and a broken display (both rolled back), a blocked local edit, and an
abandoned rebase found on the device.

* chore(auto-update): address static-analysis findings

- Replace the subprocess.CompletedProcess the verifier fabricated for a

  there, but the scanner flags any CompletedProcess built from variables.

  calls are list-form argv, no shell).
- Mark the rollback-failed message as not SQL (B608 matched its wording).

* fix(auto-update): CI failures on Linux

- Keep the setup result when chown fails. CI runs as a non-root user, where
  chown to the web user raises; that discarded the result file, so the
  General tab would never learn whether setup worked. Regression test added.
- Register the two new /api/v3/system/auto-update routes in the URL map
  snapshot.
- Use utility classes app.css defines (space-y-1, hover:text-red-600).

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(auto-update): address review feedback

- Health check: a failed restart command no longer lets the check run
  against the still-running old process; it counts as a failure (and after a
  rollback, as a failed rollback). An unreadable restart count is never
  treated as stable, since a crash loop looks healthy between attempts.
- Installer writes the auto_update setting to a temp file and swaps it in,
  keeping mode and owner, so a running config watcher never reads a
  truncated config.json.
- Verify unit quotes its command-line paths (install folders with spaces);
  setup refuses folder names systemd would reinterpret (%, quotes,
  backslashes, control characters) and says so on the General tab.
- The auto-update status route no longer returns exception text.

* fix(auto-update): keep error detail in the status route's 500

test_web_error_detail requires every 5xx handler to log the traceback and
return describe_exception(e), which redacts credentials, so failures are
diagnosable from the web UI. Dropping it for CodeQL broke that policy.

* fix(auto-update): let the app-wide handler answer status-route errors

CodeQL (py/stack-trace-exposure, #709) flagged the route's own except,
which returned describe_exception(e). web_interface/app.py's error handler
already logs the traceback and returns the same redacted detail for any
unhandled exception, so the local copy is removed: same response, no new
exception-to-response flow, and test_web_error_detail's policy still holds.

ChuckandClaude Opus 5 d01da3bd9f fix(scroll): stop timing the idle gap between scrolls as a frame (#582)
ScrollHelper.last_frame_time was set once in __init__ and thereafter only
at the end of log_frame_rate(). Nothing re-armed it when a scroll began, so
the first frame of every scroll was timed against the last frame of the
*previous* one and the whole idle period between them was recorded as a
single frame.

Measured over 3 hours on a 256x64 Pi 4, that produced 31 windows reading

    Scroll frame stats - 0.0 fps over 1 frames | median 136776.02ms
    p95 136776.02ms max 136776.02ms min 136776.02ms | stalls 0 (0.0%)

and -- worse, because it is not obviously wrong -- put the same gap in the
max field of otherwise healthy windows, where the worst values were 537s
and 604s. It also counted as one stall per scroll start: at ~500 frames to
a window that is ~0.2%, against measured stall rates of 0.07-0.16%. The
stall rate is the number used to judge whether a scroll change worked, and
it was the same order of magnitude as its own artefact.

The first frame of a scroll has no predecessor, so it has no frame time.
last_frame_time is now None until one is rendered, and reset_scroll() puts
it back -- the same treatment last_update_time already gets three lines
above, for the same reason. reset_scroll() alone is not enough, because the
scrollers actually emitting these lines never call it, so a sample at or
past the 5s log interval is dropped as well: nothing that renders a scroll
takes that long over one frame. Seeding also restarts the window timer, or
the boundary is already overdue when the second frame arrives and every
scroll opens by reporting a window of exactly one frame. A window whose
samples were all dropped now logs nothing rather than reporting the gap.

docs/SCROLL_PERFORMANCE.md documented the diagnostic in terms of a
"Frame time: N ms" line that 6031e705 replaced with the aggregate, so its
grep matched nothing on any rig. The section now describes the line that is
actually emitted, reads duplicate frames off skips and a below-median
result rather than a 2ms mode, and adds a command that ranks every scroller
by p95 -- verified against 3 hours of journal, where it reproduces
src.base_odds_manager at p95 44.08ms against 10.19ms for the two scrollers
already on src/common/scroll_config.py.

requirements.txt still offered scipy for the sub-pixel interpolation path
deleted in #570. Installing it has no effect; the entry says so.

ChuckandClaude Opus 5 814c21de1c chore: mark skins unsupported, fix stale docs and preview size, prepare 3.4.0 (#580)
* chore: mark skins unsupported, fix stale docs and preview size, prepare 3.4.0

Skins: no current scoreboard plugin builds on src.base_classes, so the only
skin hook (SportsCore._render_game) never runs. The plugin schema endpoint no
longer injects the Visual Skin dropdown, the store hides and refuses
"type": "skin" registry entries, and GET /api/v3/skins reports
supported: false with a message. Stored skin config still loads and saves.
src/skin_system/ and its tests are unchanged apart from the support flag.

Docs: check_plugin.py/render_plugin.py examples use --plugin; document
BasePlugin.get_update_interval() and its interaction with the manifest
update_interval; CLAUDE.md drops the stale template line number and
recommends display_manager.width/height.

Preview size: new src/display_geometry.py holds the size computation and
defaults DisplayManager uses (double-sided applied, chain_length default 2).
The web preview, /display/current, Starlark magnify default, sync handshake
and two dev scripts use it.

Release: __version__ 3.4.0, CHANGELOG 3.4.0 section plus a 3.3.0 tag note.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix: address CodeRabbit review on #580

- Preview fallbacks (SSE stream and /display/current) use logical_size({})
  (128x32, the shared default) instead of a hard-coded 128x64.
- display_geometry treats a non-mapping display/hardware block as missing,
  so a malformed config.json falls back to defaults instead of raising
  AttributeError (which turned the Starlark render into an HTTP 500).
- Docs: the static update interval falls back manifest -> plugin config
  -> 60s, in both the API reference and the architecture spec.

Not taken: validating double_sided copies against chain_length/parallel.
An orientation Rotate: or U-mapper pixel mapper decides which axis panels
lie on, so the counts would reject working setups (the existing
vertical-split test is one).

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(display_geometry): a non-finite hardware size raises ValueError, not OverflowError

CodeRabbit flagged the Starlark magnify default in
_standalone_render_starlark_app for truthy non-mapping display values. That
case was already handled by a9e1bd0b (_display/_hardware treat a non-mapping
block as missing, covered by test_non_mapping_display_config_uses_the_defaults),
and the magnify it produces from the 128x32 defaults is the same as from 64x32.

Checking the same path found one input that still escaped: Python's JSON
parser accepts Infinity, and int(inf) raises OverflowError, which neither the
Starlark path (TypeError, ValueError) nor the preview stream in app.py caught,
so a hand-edited "rows": Infinity returned HTTP 500. physical_size now raises
ValueError for it, matching its documented contract, so every caller's
existing fallback applies. DisplayManager already caught Exception.

ChuckandClaude Opus 5 f9b1f87e8d fix: clamp colour components, and let the style editor actually take over (#569)
* fix(element-style): clamp out-of-range colour components instead of rejecting

A regression this framework shipped. The eight scoreboards used to read their
colours through sports_card.coerce_rgb, which clamps; routing them through the
shared element_color sent them through _normalize_color, which rejected any
component outside 0..255 and fell back to the default. So a configured
[999, -5, 20] -- a typo'd bright red -- rendered white instead of (255, 0, 20).

Their own test_element_text_colors.py caught it: one case of nineteen, in all
eight plugins, failing only once the core change reached main.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): the style editor takes over its own blocks -- and gets to at all

Two defects, both found by rendering the real partial in a browser rather than
by reading the code.

It was losing a race to its own fields. The hand-off guard asked "do any
fallback controls differ from their server-rendered defaults?" as a proxy for
"is someone editing this?". But the fallback holds this block's own font
fields, and the font-selector widget populates them on the same 50ms timer --
so a plain page load, with nobody touching anything, raced into "dirty" and the
editor removed itself, leaving the 701-line accordion form it exists to
replace. Measured: seven customization.*.font selects dirty ~60ms after
injection, clean again by 400ms. The question is whether a *person* typed, and
event.isTrusted answers exactly that; the listeners now go on synchronously,
because the edit worth protecting can happen before initWidget runs.

It took over too much. Taking over removed the whole fallback section, but a
customization block can hold more than styling -- football keeps
favorite_result_colors there -- so that removed the only UI those fields had,
and the editor also rendered them as an element, giving every row an "enabled"
and three colour columns. Core now marks the blocks it recognises as styling
(the compact declaration already did; hand-written adoption did not), the
widget renders only those, and the template drops only the children the widget
reports owning.

Verified on football's real schema: 28 rows across four mode tabs, columns
Element/Font/Size/Colour/X/Y, favorite_result_colors still editable with its
ten inputs, no duplicated field names, no console errors.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): style editor no longer drops layout-only fields it never rendered

CodeRabbit flagged elementKeys() in style-editor.js: render() claims the
whole customization.layout child as the widget's own (removing it from the
generic fallback renderer, since posting the same offset twice is worse),
but elementKeys() only listed keys that also have their own top-level style
block. A hand-written schema can put a key under layout that never got one
-- a logo, a timeout indicator, a possession arrow with a position but no
font or colour -- and that key's only control silently disappeared: no row
in the style editor's table (elementKeys never listed it) and no fallback
section either (layout was removed wholesale).

elementKeys() now appends any layout-declared key not already covered by a
style element, so table() renders a row for it (layout columns only, no
style columns) and the wholesale layout ownership claim stays truthful.

Verified against current code before fixing. New regression test
(test/js/unit/test_style_editor_element_keys.js, following this repo's
existing eval-extraction pattern for testing widget JS without a browser)
fails against the reverted function and passes with the fix; added to
run_all.js and the suite table in test/js/README.md.

Full pytest suite: 4887 passed, 62 skipped, 2 failed -- both the
pre-existing Europe/Kiev/Asia/Calcutta tzdata-alias gap on this sandbox,
identical on origin/main, unrelated to this change.

* fix(web): style editor no longer strands leaf-valued layout fields

A prior fix on this PR made elementKeys() append any layout-only key with
no style block of its own (a logo, a timeout indicator, a possession
arrow), so table() draws a row for it instead of losing it when the
wholesale `layout` claim removes the generic fallback. That covers a
layout-only key shaped like an object (x_offset/y_offset, ...), because
columnsFor() only ever produced columns from a key's *sub-fields*.

It missed the case where the layout-only key's own value is itself a
leaf -- a plain "show_logo" boolean directly under layout, no x/y object
underneath. elementKeys() still lists it (any row: no matching column),
so it renders as an uneditable blank row and its only control -- the
generic fallback checkbox -- is still gone. Confirmed by executing the
real widget's render() against a synthetic schema in Node (a DOM-stub
harness, not committed): the field's name never appeared as an <input>.

columnsFor() now gives such a leaf key a column keyed to itself
('layout-leaf'), and elementRow() binds it to the leaf's own path
(customization.layout.<key>, matching the name the fallback would have
used) instead of leaving every cell blank.

New regression test (test/js/unit/test_style_editor_layout_leaf_columns.js,
following this PR's existing eval-extraction pattern) checks the leaf
column is produced, is self-keyed, doesn't duplicate, and that a schema
with no leaf-valued layout key is unaffected; wired into run_all.js and
the suite table in test/js/README.md.

test/js/run_all.js: 84 + 6 + 6 = all suites passed (jsdom unavailable
here, DOM suites skip as before). Python suite untouched by this change;
test_style_editor_extra_fields.py, test_style_editor_save_roundtrip.py
and the one PIL-dependent style_editor_takeover.py case fail identically
before this commit -- missing flask/PIL in this sandbox, not this PR.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): keep layout-leaf style-editor columns distinct from name collisions

columnsFor() keyed a layout-only leaf field's column by its bare field
name. If an unrelated element's style block or another element's layout
axis block happened to declare a sub-field with that same name, the
`!seen.has(key)` guard skipped creating the leaf's column, silently
dropping its only control again -- the same failure the leaf-column fix
was meant to close, just reached through a name collision (CodeRabbit
review on 324a7ea).

Key layout-leaf columns under a namespaced id so they can never be
shadowed by an unrelated column sharing their name.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): CSS.escape() the owned key before it becomes a selector

container.dataset.ownedKeys round-trips schema property keys through a
DOM dataset attribute, and the takeover handoff spliced each one
straight into '[data-child-key="' + k + '"]' with no escaping --
inconsistent with this codebase's own convention elsewhere
(plugin-file-manager.js, app-shell.js's escapeCssSelector) for building
a selector from a dynamic value. A key containing a quote or backslash
would break the selector or be steerable; Codacy's static analysis
flagged this pattern (1 high ErrorProne finding on PR #569, current
head at the time) as a new issue, though its dashboard is unreachable
from this sandbox (egress to app.codacy.com is blocked) and the
check-run API returned no detail text -- verified and fixed by reading
the diff directly rather than the tool's own description.

Added a source-assertion regression test alongside this file's
existing ones (this behavior lives in an inline script no Python test
executes).

Full suite: 4888 passed, 62 skipped, 2 failed -- both the pre-existing
Europe/Kiev/Asia/Calcutta tzdata-alias gap in this sandbox, identical
on origin/main, unrelated to this change.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* feat(web): every advertised layout offset gets a control in the style editor

The editor took the whole layout section over but matched offsets to style
rows by exact key. A hand-written schema's two blocks were never named alike --
football styles score_text but positions score -- so of football's eleven
positionable things only status_text had a control. Score, odds, both logos,
timeouts, possession, down-and-distance, date, time and records were options
the schema advertised and the renderer reads, reachable nowhere in the UI.

Core now resolves each style element's layout key through alias_keys, the map
the resolver already reads offsets with, and records it as x-layout-key. The
widget reads that rather than carrying a second copy of the rules, and posts
under the key the schema declares: football's own offset reader looks up
layout.score, so a value saved as layout.score_text would be kept and never
drawn. Layout entries no style element claims get an "Other positions" table
with its own columns, in every mode panel as well as the base one, in the order
the plugin declared them.

Verified in a browser against football's real schema: 92 of 92 layout fields
(23 base, 23 per mode) rendered exactly once under their declared names, none
posted under a style key, no duplicated field names, favorite_result_colors
still editable.

ChuckandClaude Opus 5 7e580dc005 fix(wifi): make Connect work from the setup AP (#571)
* fix(wifi): make Connect work from the setup AP

Joining a network from LEDMatrix-Setup has to take the AP down first, which
drops the phone that sent the request. The connect endpoint answered only
after the attempt finished, so the browser never got a reply and the WiFi
tab's Connect button appeared to do nothing.

- /wifi/connect answers 202 immediately while the AP is active and connects
  in a background thread; the result (never the password) is reported via
  /wifi/status as last_connect_attempt. A second connect while one is
  pending gets 409.
- connect_to_network holds a /tmp flag for the attempt; the monitor daemon
  skips AP management while it is fresh. Previously the daemon's
  disconnected counter, accumulated over the whole AP session, re-enabled
  the AP on its next tick in the middle of the connect.
- The WiFi tab and captive setup page explain the handoff up front, and on
  reopening show why the last attempt failed. The wrong-password message
  now works: the route sets the error_type the captive page checks.

* fix(wifi): serialize connect attempts on both paths

Addresses CodeRabbit review on #571:

- Check for a pending attempt before branching on AP state. A background
  attempt takes the AP down long before it finishes, so a second click
  used to bypass the 409 and start a competing synchronous connect.
- Record pending for the synchronous (non-AP) path too, so two requests
  can't overlap and have the first clear the daemon's in-progress flag
  while the second is still connecting.
- Clear the pending state if the background thread fails to start, rather
  than refusing every later request until restart.
- Say the setup network returns "within a few minutes": a stale flag plus
  the daemon's grace period can take longer than one.

ChuckandClaude Opus 5 d51f7ada14 chore(scroll): drop the dead sub-pixel path, and two dev-tooling papercuts (#570)
Three independent changes, none of which alter runtime behaviour.

1. Remove ScrollHelper._get_visible_portion_subpixel and
   _interpolate_subpixel (162 lines). get_visible_portion dispatches only to
   _blend_visible_portion, so _get_visible_portion_subpixel had no caller, and
   _interpolate_subpixel was reachable only from inside it -- a closed island.
   _blend_visible_portion's own docstring already records that the scipy path
   it replaced was dead; the replacement landed but the corpse stayed.

2. scripts/check_plugin.py: also search ../ledmatrix-plugins/plugins. The
   scoreboards live in the sibling checkout, so --all silently skipped every
   one of them and only --plugin-dir reached them.

3. .gitignore: ignore config/.config_secrets.json.tmp.*, which the suite
   leaves behind several of per run.

ChuckandClaude Opus 5 69d408b321 feat(core): one per-element display-customization framework, wired into the web UI (#566)
* fix(sports): rebuild un-shared faces through the pinned layout engine

unshare_element_fonts re-instantiates a duplicate font face so two
elements can be told apart by id(). It did so through bare
ImageFont.truetype, which takes PIL's default layout engine rather than
the one src/common/font_layout.py pins. Raqm and Basic disagree on
fractional advances -- that disagreement is the reason the pin exists,
having broken golden images across machines -- so a rebuilt face could
measure differently from the shared face it replaced, on any host where
Raqm is installed.

These were the only two call sites in src/ bypassing the pin.

The guard asserts that the rebuild goes through the pinned loader rather
than comparing engine values: where Raqm is absent, bare truetype returns
BASIC anyway, so an engine comparison passes whether or not the pin is
honoured. The first draft of this test did exactly that and passed with
the bug reintroduced.

* refactor(web): drop the two dead client-side config-form renderers

generateConfigForm and generateSimpleConfigForm (580 lines) were defined
on the Alpine component and never called: server-side Jinja replaced them,
as pages_v3.py:641 records. Nothing in any template invokes them -- there
is no x-html in the templates and no bracket access on the component.

They carried their own x-widget dispatch, which made them an active trap:
the next person adding a widget would reasonably think both renderers
needed updating.

plugins/config_manager.js (PluginConfigManager, 133 lines) goes for the
same reason -- loaded on every page from base.html, referenced only by
itself and by an archived doc.

Kept, having checked them: widgets/example-color-picker.js is the worked
example docs/widget-guide.md points plugin authors at, and
widgets/plugin-loader.js is the client half of a documented feature
(manifest-declared plugin widgets) whose server route is missing --
soccer-scoreboard already ships a widgets/custom-leagues.js that this
loader is meant to fetch. That is an unfinished feature to complete, not
dead code to delete.

* feat(web): serve plugin-declared widgets, and actually ask for them

LEDMatrixWidgets.loadPluginWidget has always fetched
/static/plugin-widgets/<plugin>/<widget>.js, and docs/widget-guide.md has
always documented that path, but nothing served it. soccer-scoreboard has
shipped a 17KB widgets/custom-leagues.js since August that could never
load. Both halves were missing, not just the route:

- serve_plugin_widget serves the script from the plugin's widgets/
  directory as text/javascript. The manifest is the allowlist -- only a
  widget the plugin declares is reachable -- so installing a plugin does
  not publish everything it ships. Path handling mirrors the sibling
  serve_plugin_web_ui: allowlist regexes, os.path.basename, resolve() +
  relative_to() containment, and the ledmatrix- prefix fallback. The
  declared script name is guarded too, since it comes from the plugin
  rather than the request.

- The config form never requested one. Its x-widget dispatch is a
  hardcoded list of core widget names, so a plugin's own widget fell
  through to a plain text input. An unrecognised x-widget on a string
  field now asks ensureWidget() for it. The text input stays as the
  fallback and is removed only once the widget has actually rendered, so
  a missing or broken widget costs the user an editor rather than their
  configured value on the next save.

- manifest_schema.json gains "widgets", so the declaration is validated
  rather than merely tolerated by additionalProperties.

Verified in a browser against the real partial: a declared widget loads,
registers and renders, and its field posts exactly one value; a field
whose widget 404s keeps its text input and still posts its value.

Not addressed: loadPluginWidgetsFromManifest still has no caller. The
per-field ensureWidget path is lazier and is what the form now uses, so
that bulk helper is dead weight -- worth removing, but left alone here
rather than inventing a call site for it.

Known limitation, documented: only string-typed fields take this path.
object/array/boolean/number fields and enums are dispatched by the
template's own branches, which still only know core widgets.

* fix(element-style): a wrong-size BDF now keeps its font, not its size

BDF fonts are fixed-size bitmap strikes: FreeType accepts only the pixel
size baked into the file and raises for anything else. 32 of the 35
shipped fonts are BDF, so a size picked in the web UI usually is not a
valid strike -- and load_font caught that failure with its generic
"unloadable font" handler, which substitutes PressStart2P. Asking for
5x7.bdf at size 10 therefore rendered a completely different typeface,
silently.

It now falls back to the file's own native size instead, which is what
SportsCore._load_custom_font_from_element_config has always done. The
native size is read via FontManager._read_bdf_native_size rather than a
fourth copy of that parser, matching how core.py already delegates.

Also here, because they are the same code path:

- native_bdf_size() is exposed for the web UI, which needs to know when a
  size field can take effect at all. None means "free choice".
- ElementStyle.font_size now reports the size actually realised rather
  than the one requested. Callers lay out from it, and reserving space
  for a size nothing was drawn at is how this surfaces.
- The module font cache is a bounded LRU (256) instead of an unbounded
  dict. The display process runs for weeks and every config save can add
  a (font, size) pair; every other hot cache in the codebase is bounded
  this way.

Untouched configs are unaffected: the shipped classic fonts are the three
TTFs, so nothing was hitting the substitution path by default.

* feat(element-style): per-mode style and offset overrides

Lets one element be styled differently per situation -- a scoreboard's
live / upcoming / recent cards, weather's current / hourly / daily
screens -- under customization.modes.<mode>.

The mode is bound at construction rather than passed per call. That is
what makes this cheap to adopt: SportsUpcoming and SportsRecent are
already separate instances with distinct SKIN_MODE values, so binding
once makes every existing style()/offset_value() call site mode-aware
without editing any of them. A per-call mode argument exists for the rare
host that renders more than one mode.

The two layers answer different questions, deliberately:

- The base layer keeps the existing "differs from the schema default"
  rule, because the save flow writes the full default object into
  config.json whether or not the user touched it.
- A mode layer is pure override -- its fields default to None, so
  presence is intent. Nothing writes into it unasked, so there is nothing
  for the stricter rule to protect against.

None therefore means inherit, and has to stay distinct from 0: a mode
y_offset of 0 means "sit at the base position", not "no preference".
This is the same distinction scroll_card.switch_* draws with "inherit".

A malformed mode value falls back to the resolved base value rather than
to the caller's default -- caught by the degradation tests, which is what
they are for: resolving the mode first let one bad string in a mode block
silently discard a good base offset.

With no modes block, and for every existing caller, resolution is
unchanged.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* feat(element-style): declare per-mode overrides in config_schema.json

A plugin adds "x-style-modes": ["live", "upcoming", "recent"] alongside
its x-style-elements declaration and gets a customization.modes.<mode>
group per mode, with every field of every declared element repeated as an
override.

Those override fields are typed nullable and default to null, which is
the whole trick. The save flow writes schema defaults into config.json
wholesale, so giving a mode field the base element's default would make
every mode a frozen copy of the base the first time a user pressed Save,
and the base would stop reaching them. Null means inherit. The mutation
test for this is explicit: with concrete defaults, a base font_size of 14
resolves as 10 with user_forced set.

min/max from the declaration carry into the mode blocks, so an
out-of-range override is rejected by validation rather than clamped
silently at render time.

Also: the emitted font field now carries "x-widget": "font-selector". The
widget already shipped and the config form already allowlisted it -- the
hint was simply never emitted, so the field rendered as a bare text box
that the user had to type a font filename into.

Verified through the real SchemaManager path -- load_schema, defaults
extraction, merge_with_defaults, validation, then resolution -- rather
than against a hand-built dict, since the thing at risk is what that
pipeline does to a null.

* fix(web): render the config form from the schema the save route validates

The form read config_schema.json with a raw json.load while
api_v3.save_plugin_config went through SchemaManager. Those are not the
same schema: SchemaManager applies expand_style_elements, which turns a
compact customization.x-style-elements declaration into the per-element
blocks the form knows how to render.

Without it, that customization object has an x-style-elements key and no
"properties", so the template's object branch matched nothing and the
section rendered as empty space -- while saving still validated against
the expanded shape. of-the-day ships the compact form, so its
customization section has been invisible in the web UI.

pages_v3 gains a schema_manager the way it already has config_manager and
plugin_manager. use_cache=False matches the save route, so an edited
schema is not served stale during plugin development. The raw read stays
as a fallback for callers that register this blueprint without one.

Checked before making the change: load_schema does nothing here except
read, validate and expand -- inject_skin_selector is a separate method it
does not call -- so this is not a behaviour change for schemas without
the declaration.

The test pair renders the same compact schema with and without a
SchemaManager, so it documents exactly what was broken as well as what is
fixed.

* feat(web): style-editor widget -- a row per element instead of 65 accordions

Rendered element by element, a realistic scoreboard's customization block
is 65 nested sections, and reaching one per-mode font size takes five
levels of expanding. The widget collapses that to one compact row per
element -- font, size, colour, X, Y -- with a tab per declared mode.

It emits ordinary inputs under the same dotted names the generic renderer
would produce, so the save/validate/merge pipeline is untouched: no hidden
JSON blob and no new server-side parsing. It is driven entirely by the
schema block it is handed, so fields added to the schema later appear
without editing the widget. If it fails to load or throws, the generic
nested rendering it replaces is left in place.

Fixing two things the save path got wrong for nullable fields, found by
posting what the widget actually emits:

- The indexed-array recombiner (text_color.0/.1/.2 -> one list) compared
  the declared type to the string 'array', so a per-mode colour, typed
  ["array", "null"], was never reassembled and failed validation on save.
  _parse_form_value_with_schema had the same comparison.
- A blank nullable field became [] rather than None, which then failed the
  minItems the colour array declares. Null is the inherit sentinel, so it
  has to survive.

And two things the widget itself got wrong, found by looking at it:

- An unset base control fell back to the select's first option, so an
  untouched scoreboard claimed every element used 10x20.bdf -- and the
  size box then locked itself to that bitmap font's fixed size. Base
  controls now show the schema default; mode controls stay blank, because
  blank there means inherit.
- Elements arrived alphabetised (Detail and Odds above Score). Flask's
  JSON provider sorts keys, so declaration order has to be stated
  explicitly; expand_style_elements now emits x-propertyOrder, which the
  generic renderer already honoured too.

Size is disabled and shown as fixed for a bitmap font, using the
scalable/native_size the font catalog now reports.

* feat(element-style): visibility, alignment and scale per element

Completes the customization vocabulary: hide an element, align it, and
resize a logo, alongside the font/size/colour/offset that already existed.
All three per mode.

They resolve to "change nothing" until the user asks for something -- True,
None and 1.0 -- rather than to whatever the schema declares. That is the
same invariant the font fields keep: a caller that honours them still
renders an untouched config exactly as it did before they existed. A
schema default therefore does not count as a choice, which matters because
the save flow writes that default into config either way.

scale sits in the layout block with the offsets rather than in the element
block, because it is geometry: a logo has a scale and no font. The widget's
columns come from the schema, so a logo row shows visibility, offsets and
scale and no empty font cell.

Two bugs found by the tests rather than by reading:

- A nullable enum needs null in its enum list, not just in its type. The
  mode copy of `align` defaulted to null and then failed its own schema, so
  a plugin declaring any enum field with modes could not save at all. Six
  tests failed on this before any of them reached what they were testing.
- defaults_from_schema only ever extracted font/font_size/text_color, so
  the schema defaults for the new fields were invisible to the resolver and
  a declared default read as a user choice.

Widget: the table scrolls horizontally and pins the element-name column.
Nine columns do not fit the config panel, and clipping them hid the offsets
entirely while scrolling them made every row anonymous.

* feat(element-style): resolve elements under the names plugins actually use

Two naming conventions collided as the scoreboards grew. Counted across
the published schemas: the style block names elements with a _text suffix
(score_text, status_text, detail_text), while the layout block mostly uses
the bare noun (score, date, time, odds) -- except status_text, which kept
the suffix in seven plugins and lost it in two. records vs record splits
seven to two the same way.

A lookup now tries the exact name first and then the spellings that mean
the same thing. Exact-first is what makes this inert for any config that
already matches; the aliases only decide cases that resolved to nothing
before.

This is also what makes migrating to the compact declaration form safe.
That form uses one key for both blocks, so a scoreboard adopting it asks
for layout.score_text while its users have layout.score saved -- without
the aliases, every offset they had dialled in would silently become 0.

Applies to the style block, the layout block, the schema defaults and the
per-mode overrides, since the drift shows up in all four.

Not attempting to canonicalise on write: renaming keys in config.json
would break the plugins still reading the old spelling from their own
bundled code, and the drift costs a dict miss rather than correctness.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* feat(plugins): BasePlugin.styles -- per-element styling every plugin inherits

Adopting the element-style system meant repeating three things in every
plugin: a guarded import, finding its own config_schema.json, and
rebuilding the resolver when on_config_change swapped the config dict.
This is those three things once, on the class all 45 plugins already
inherit from.

    title = self.styles.style('title_text',
                              classic_font='PressStart2P-Regular.ttf',
                              classic_size=8, classic_color=(255, 255, 255))

The classic_* arguments are the adoption contract: with nothing configured
they come back verbatim, so a plugin that switches to this renders exactly
as before until a user changes something.

A plugin with one instance per display mode sets STYLE_MODE on the class
and every existing lookup becomes mode-aware without a call site changing
-- which is the point of binding the mode to the resolver rather than
passing it per call. styles_for() covers a plugin that renders several
modes from one instance.

Schema discovery reads the concrete class's own module rather than this
file, because this file lives in src/plugin_system where no plugin schema
exists -- the same trap SportsCore._config_schema_path documents. The
first mutation test for that passed anyway: an installed plugin's module
directory and its entry under plugins_dir are the same path, so the test
could not tell the two apart. The case where they diverge is a plugin
symlinked in for development, and the test now forces that shape.

Getting discovery wrong is silent rather than loud: with no schema the
resolver has no defaults to compare against, so every configured value
reads as a deliberate override and the plugin quietly stops honouring its
own shipped styling.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* feat(element-style): adopt hand-written customization blocks, and widen the font list

Nineteen plugins spell their style elements out longhand instead of
declaring them -- football's block is 701 lines for seven elements -- and
predate this system entirely. Core now recognises that shape, so they pick
up the row-per-element editor and the real font picker on a core update
rather than on a plugin release. Checked against every published schema:
21 plugins adopt, and the defaults of each still validate against the
schema generated for it.

Detection requires *every* field in a block to be one this system
understands. A looser "has at least one style field" rule sweeps in
baseball's `count`, which carries a text_color beside geometry that means
nothing here. That distinction took three attempts to test: the first two
assertions passed under both rules, because an over-eager rule leaves a
fontless block looking untouched and only surfaces as an extra row in the
editor.

The hardcoded font enum is replaced rather than extended. Football lists
five of the thirty-five installed fonts, which is why a font a user
uploads can never appear in one. It is not a curated safe set -- it omits
some twenty other faces that fit the declared size cap just as well -- it
is the fonts that happened to exist when it was written.

Widening it does need a guard, though, and not the one the schema already
has: a bitmap font ignores font_size and renders at its size baked into
the file, so `maximum: 16` cannot stop a 27px face. The picker now filters
out fixed-size fonts taller than the element's own declared ceiling, which
drops exactly the four that would overflow a 32px panel and keeps the
other thirty.

Per-mode overrides stay opt-in: core cannot invent a plugin's display
modes, so `x-style-modes` remains the one line that unlocks them. Their
layout half covers every positionable element rather than only those with
a style block -- the two namespaces do not line up in a hand-written
schema, and football positions six things (logos, timeouts, possession)
that have no style block at all.

* refactor(web): remove the two Fonts-tab panels that reported invented data

"Element Font Overrides" let a user configure an override, showed a
success toast, and changed nothing. All three endpoints behind it were
stubs -- GET returned a hardcoded {}, POST and DELETE returned success
without calling anything -- each marked "This would integrate with the
actual font system".

Wiring them to FontManager would not have fixed it. The machinery there is
real (_load_overrides/_save_overrides persist config/font_overrides.json,
resolve_font applies them, and the countdown plugin genuinely consumes
it), but the panel's element dropdown offered eleven invented keys --
nfl.live.score, clock.time, weather.current -- that no plugin has ever
read. An override saved against one of those would have persisted
correctly and still done nothing.

"Detected Manager Fonts" goes for the same reason. It claimed to show
"fonts currently in use by managers (auto-detected)"; its own comment said
"we'll simulate this", and it listed every font in the catalog with a
hardcoded usage_count of 1 -- the panel beside it, with fabricated
numbers attached.

Per-element font choice now lives in each plugin's own config editor,
against the elements that plugin actually has, and covers size, colour,
offsets, visibility, alignment and scale rather than family and size.

Kept: the font library (upload, preview, delete), which works, and
/fonts/tokens, which is a stub but genuinely feeds the preview's size
dropdown. FontManager's override methods are untouched -- countdown uses
them.

Verified in a browser with the tab's JS running: no console errors, 35
fonts listed, upload and preview intact. Removing the panel meant unwiring
it from populateFontSelects too, which would otherwise have bailed out
early on the missing select and left the preview dropdown empty.

* refactor(sports): one reader for element colours and layout offsets

There were two copies of the per-element colour read and three of the
layout-offset read. They had already drifted -- the scroll-card renderer
carries a comment about having ignored offsets its own schema advertised
-- and each new capability had to be added to all of them or silently work
in some places and not others.

All of them now go through src.element_style, which is what carries the
alias handling and the per-mode lookup. That lands immediately for the
nine plugins importing these modules: a scoreboard asking for `score_text`
offsets finds the `layout.score` its users configured, and a Live instance
resolves its own colours through SKIN_MODE without any call site passing a
mode.

_normalize_color learned "#RRGGBB" in the process. The scoreboards' own
readers have always accepted it, so the shared one had to, or consolidating
would have quietly dropped a form users' configs may hold. _coerce_offset
picked up the non-finite guard the scroll-card reader had and the other two
did not.

_get_layout_offset is promoted onto SportsCoreSharedMixin. Each plugin
still carries its own copy in its bundled sports.py, which wins by MRO --
so adopting this is a deletion in the plugin, and until that deletion
nothing changes for it.

Note for whoever runs the suite next: test_display_dirty_tracking.py is
order-dependent. Fifteen of its tests failed in one full run and passed in
the next with no change in between, and pass in isolation. Pre-existing,
unrelated to this, but it makes a full-run diff untrustworthy until it is
fixed.

* docs(changelog): record the element-style work under Unreleased

This file's own preamble asks for it: a plugin may delete its bundled
fallback copy of a core module only when its manifest floors on the first
release that shipped that module, which requires the additions to be
recorded here against a version.

Names a plugin can now import and floor on -- the stateless layout_offset
and element_color readers, alias_keys, native_bdf_size, the resolver's mode
binding, BasePlugin.styles, and the promoted
SportsCoreSharedMixin._get_layout_offset -- plus the schema and web-UI
changes, the four fixes and the three removals.

* fix(fonts): log the BDF native-size read failure instead of swallowing it

The bdf-native-size lookup in get_fonts_catalog() caught any exception
and silently discarded it. Every other guarded read added in this PR
(the manifest parse in _declared_widget_script, the SchemaManager
fallback in _load_plugin_config_partial) logs before falling through
to the same degraded behavior. This one didn't, which is the shape a
silent-exception-swallow lint rule flags. Behavior is unchanged --
native_size still comes back None -- but a corrupt or unreadable BDF
file now leaves a trace.

Verified: font-related tests (140) and the full suite still pass,
with only the 2 pre-existing Europe/Kiev/Asia/Calcutta tzdata-alias
failures already present on origin/main.

* fix: address CodeRabbit findings on the style-editor/font-selector PR

- Fix _load_font_sized double-wrapping the (font, size) tuple on the
  missing-font path, which handed callers a tuple instead of a font.
- Fix _set_nested_value skipping an explicit None when the key already
  existed, which silently kept stale overrides when a user cleared a
  nullable per-mode field or blanked all channels of an indexed color.
- Preserve BDF scalable/native_size metadata through fetchFontCatalog's
  catalog-format mapping so maxFixedSize filtering actually applies.
- Stop caching an empty array on a failed font-catalog fetch so a later
  call can retry instead of being stuck with the failed result.
- Keep a saved font selected in the style editor even when it no longer
  fits a newly declared maxFixedSize, instead of silently deselecting it.
- Don't drop in-progress user edits to fallback fields when a plugin
  widget finishes loading asynchronously and takes over the form.
- Tighten the removed font-override endpoint test to assert 405, not
  just != 200.

* fix(web): a partial save no longer switches off checkboxes it never showed

An HTML checkbox posts nothing when unchecked, so the save route walked the
schema and forced every boolean missing from the form to False. That is right
for the rendered form and wrong for every other caller: a script, the MQTT
bridge or a curl against the documented endpoint never rendered a checkbox, and
reading its silence as "all off" turns a one-field save into a mass disable.

Found on hardware. Posting four customization.* keys to a live device switched
off nfl.enabled, ncaa_fb.enabled and every display-mode toggle in one request.

The form now reports the top-level sections it drew (__rendered_section), and
inside those an absent checkbox still means unchecked -- including a section
whose only fields are checkboxes that are all off, which no heuristic could
recover. A post with no marker only touches objects it actually posted a field
from. Meta fields are dropped before form keys are treated as config paths,
because unknown keys are otherwise written straight into config.json.

* feat(sports): resolve element colour by name, and honour visible/align/scale

Two of the three gaps this framework shipped with.

Colour by name. A draw resolved its colour by comparing the *identity* of the
font object it was handed, which cannot tell two elements apart when they share
a face -- so those draws went out white. Every bitmap font is in that case,
because a freetype.Face cannot be re-instantiated to un-share it, which is how
an element rendered in any of the 32 shipped BDF fonts silently lost a colour
its picker had offered all along. _draw_text_with_outline now takes
element="score_text" and reads the colour by name; the identity path remains
for un-annotated callers, but narrows before giving up -- one configured colour
among the sharers is the only thing the user can have meant.

Visible, align and scale. The resolver has understood these since the
framework landed and nothing consumed them: an element could be marked hidden
in the web UI and still render. Adds the stateless readers, the mixin
accessors, and a scale parameter on the one shared logo-sizing seam (keyed into
the cache, so two elements scaled differently cannot be served each other's
image). Naming an element in a draw also honours its visibility.

Untouched configs are unaffected: every new parameter defaults to today's
behaviour, and all ten affected plugins render pixel-identically to main across
every harness size.

* docs(plugins): how to declare styleable elements; harden the widget's lookups

The plugin-author guide for the compact x-style-elements declaration -- what
each key does, how to read values back without breaking the "user-forced only
when it differs from the default" rule, and why a hand-written block needs no
changes to be adopted.

Also clears the static-analysis findings on style-editor.js. Every lookup in
that file is keyed by something out of a schema or a saved config, so a key of
__proto__ or constructor would walk the prototype chain and hand back a
function instead of a schema; reads now go through an own-property helper. The
panel registry became a list, and the flagged vars moved to their function
roots.

* fix(web): clear the remaining static-analysis findings

Five, all on lines this branch touched.

The Python one is not a new defect: _set_missing_booleans_to_false's first
parameter was always named `config`, which shadows the `config` submodule
imported for its side effects at the bottom of this module. Editing the
signature simply put the existing warning on a changed line. The parameter is
the plugin's config dict, so `plugin_config` is what it should have been called
anyway; callers pass it positionally and are unaffected.

The JavaScript ones are the object-injection rule firing on reads keyed by
data. own() now goes through a property descriptor, so the one unavoidable
data-keyed read is no longer a computed member access; at() consumes its path
instead of indexing it; and the column set is a Map, which has no prototype to
pollute and needs no guarded reads at all.

Verified the widget still renders identically against football's real schema:
29 element rows, all four mode tabs, values populated, no console errors.

* fix(web): drop the hasOwnProperty alias the descriptor read made redundant

own() now reads through Object.getOwnPropertyDescriptor, so the alias it used to call has no remaining reference.

ChuckandClaude Opus 5 92ac231138 fix(fonts): load 4x6 on its pixel grid, from any working directory (#565)
* fix(fonts): load 4x6 on its pixel grid, from any working directory

`extra_small_font` loaded 4x6-font.ttf at 6, off the face's 7px grid.
Under `draw.fontmode = "1"` the mono rasteriser thresholds each glyph at
50% coverage, so every glyph lost its fourth column and deformed:
christmas-countdown rendered "UNTIL" as "VM1JL". The advance is 5px at
both sizes, so snapping to 7 reflows nothing.

- Sizes in DisplayManager._load_fonts go through crisp_size() instead of
  literals. crisp_size / FONT_PIXEL_GRID / FONT_NAME_ALIASES move to
  src/common/font_layout.py; sports_card re-exports them.
- Mirror the fix in VisualTestDisplayManager, the harness's fork of
  _load_fonts. Without it every golden is blessed at the old size.
- Resolve bundled font paths against the install root, not the cwd.
  FontManager._resolve_asset_path now delegates to
  font_layout.resolve_asset_path (kept by name; plugins probe for it).
- The startup banner's middle rung snaps to 7; the 5 rung stays off-grid
  on purpose (the only size that fits a dotted quad on 64px).
- loading.py reads all plugin JSON as UTF-8 (cp1252 on Windows aborted
  check_plugin.py on a 0x9d byte).
- check_plugin.py reports in ASCII and never dies on an unencodable char.

* fix(fonts): resolve relative asset paths from the install root, not the cwd

resolve_asset_path checked os.path.exists(relative_path) unconditionally,
so a relative asset path was still resolved against the process cwd first
-- exactly the dependency this module exists to remove. An unrelated
working directory that happens to contain assets/fonts/4x6-font.ttf (a
stale checkout, a copied assets folder, another project) would shadow the
real bundled font instead of the install root ever being consulted.

Only an absolute path is now returned as-is; a relative path always
resolves against _INSTALL_ROOT first, matching the docstring's stated
contract. FontManager._resolve_asset_path delegates to this function, so
it's covered by the same fix.

ChuckandClaude Opus 5 9ad7528c9b fix(config): stop same-second backups overwriting each other (#564)
* fix(config): stop same-second backups overwriting each other

A backup's version is its identity. save_config_atomic() hands the path
back, rollback_config(backup_version=...) looks that version up, and the
paired secrets backup is found by reusing the same string.

The version was stamped at second granularity, so two saves inside the
same second produced the same filename and the second shutil.copy2()
silently overwrote the first backup. The path a caller was still holding
then pointed at different content, and rolling back to it restored the
wrong config. A user saving twice in quick succession lost a restore
point with no error.

list_backups() made it worse. It parsed the version off Path.stem, which
drops only the last dot-component, so for config.json.backup.20240101_120000
parts was ['config', 'json', 'backup'] and parts[-2] was 'json' -- never
'backup'. The filename branch was unreachable: every backup fell through
to the mtime fallback and reported a second-granularity restamp of its
mtime rather than the name on disk, so a unique filename alone would not
have been enough for rollback to find the right version.

Stamp microseconds, and never overwrite an existing backup -- on a
collision bump a -N suffix rather than lose a restore point. Parse the
version off the exact glob prefix so it round-trips with the filename,
still reading the legacy second-granularity format so restore points that
predate this keep working.

Two tests had encoded the bug:

  - test_multiple_config_changes asserted a rollback produced plugin1=45
    with plugin2=15, a state no single backup ever held -- 45 was only in
    the second backup, 15 only in the first. It passed because the two
    saves collided onto one file, so the first version resolved to the
    second's content. Corrected to the state that backup actually holds.

  - test_backup_rotation asserted against a hardcoded max of 3 while
    setUp configured 5, and still passed: every save in its loop collapsed
    onto a single filename, so there was only ever one backup to count and
    rotation was never exercised. It now asks the manager for its limit
    and overshoots it.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(config): fold collision suffix into ordering, close backup-path race

_parse_backup_version() stripped any trailing "-segment" unconditionally,
so a collision-suffixed backup parsed to the exact same timestamp as its
sibling and list_backups() had no deterministic way to order them. Only
strip the suffix when it's numeric, and fold it back in as extra
microseconds so same-tick collisions sort newest-first reliably.

_create_backup() also checked backup_path.exists() before shutil.copy2(),
which two concurrent callers can both pass for the same path -- the second
copy2() then silently destroys the first call's restore point. Reserve
each path (config and, when configured, secrets) with exclusive file
creation instead of a check-then-copy, retrying on a real conflict.

ChuckandClaude Opus 5 f6367d63ae security: triage the CodeQL backlog — 129 alerts, three of them live (#561)
* fix(web): escape quotes in every HTML escaper, not just & < >

The escapers are all `div.textContent = x; return div.innerHTML`. That
round-trip escapes &, < and > -- the only characters the HTML serializer
must escape in a text node -- and leaves quotes alone. Every widget then
interpolates the result into a quoted attribute value:

    value="${escapeHtml(v)}"   title="${escapeHtml(v)}"

so a value of `x" onmouseover="alert(1)` closes the attribute and adds an
event handler of its own. CodeQL reported this 83 times
(js/incomplete-html-attribute-sanitization) across the widget files.

It is one bug, not 83: the widgets each carry a standalone fallback that
did escape quotes, but they all prefer BaseWidget.escapeHtml when
window.BaseWidget exists -- which it always does in the shipped page -- so
the correct fallbacks were dead code and the incomplete shared one ran.
Fixed at each source instead of at the call sites.

app-shell.js already documented this exact gap in a comment and worked
around it by building DOM nodes by hand; that workaround stays (setting a
property cannot be got wrong), the comment is now accurate.

cache.html's delete button interpolated the cache key into
`onclick="deleteCacheFile('...')"`. Escaping cannot help there -- the
browser HTML-decodes the attribute before parsing it as JS, so `&#39;`
becomes a real `'` again -- so the key moves to a data-cache-key
attribute that the handler reads back.

url-input.js additionally wrote a value straight into an <a href> after
validating it against a schema-supplied protocol list, and that list
accepted any RFC 3986 scheme -- "javascript" included. Scriptable schemes
(javascript, data, vbscript, blob, filesystem) are now refused both when
the list is normalised and when a URL is checked against it, and the
render path routes its href through the same check instead of emitting
whatever was stored (js/xss-through-dom).

test/js/unit/test_html_escaping.js reads each escaper out of the shipped
file and runs it, so losing the quote handling again fails a test rather
than a scan.

* fix(security): stop request-supplied names from reaching paths outside their base

Three of the py/path-injection alerts were live, not lint:

* GET /api/v3/plugins/<plugin_id>/static/<path:file_path> read any file
  whose resolved path *string-prefixed* the plugin directory. Flask's
  default converter forbids a slash but not dots, and
  get_plugin_directory('..') returned the parent of the plugins directory
  because it exists -- so every file under the project root then prefixed
  that directory, config/config_secrets.json included. The prefix check
  was also wrong on its own terms: with plugin dir "plugin-repos/foo",
  "../foo-evil/x" resolves to "plugin-repos/foo-evil/x", whose string does
  start with "plugin-repos/foo".

* POST /api/v3/plugins/of-the-day/json/delete interpolated the request
  body's file_id into f"{file_id}.json" and unlinked it, unvalidated. A
  file_id of "../../../../etc/something" deleted that file. This is the
  one finding in the batch that destroyed data rather than exposing it.

* POST /api/v3/cache/delete passed the body's key through
  CacheManager.clear_cache to DiskCache, which joined it as a filename and
  called os.remove. Same shape, same result. The guard goes in
  DiskCache.get_cache_path, the single choke point get/set/clear share, so
  every caller is covered rather than just this route. Real keys are the
  stems of files already flat in the cache directory -- that is how
  list_cache_files derives them -- so nothing legitimate is turned away.

The rest of the cluster (web_interface/app.py's asset route, the plugin
update handler, _get_plugin_version, the plugin-schema read in config.py)
was guarded in ways that held, but each had grown its own version of the
check. They now go through one helper, src/common/path_safety.py, which
returns the *sanitised value* rather than a verdict -- so a caller cannot
validate one string and open another, which is how the two real bugs
above were shaped.

Also: WiFiManager.connect_to_network took the SSID and password straight
from POST /api/v3/wifi/connect into nmcli's argv. There is no shell there,
so CodeQL's py/command-line-injection alert overstates the risk -- but
nmcli reads a leading "-" as an option, so an SSID of "--ask" asks nmcli
to run differently rather than to join a network. Both values are now
checked for shape (802.11's 32-octet SSID limit, WPA's 8-63 char
passphrase or 64-char hex key, no control characters, no leading dash)
before any subprocess runs.

test/test_path_traversal_guards.py asserts on the filesystem, not just
the status code: a handler that returns 403 and deletes the file anyway
would pass the weaker check. Twelve of its cases fail against the
unpatched code.

* fix(web): refuse a plugin id that is not a plain name, don't truncate it

pages_v3 and scripts/dev_server.py ran request ids through
os.path.basename and carried on with what came out, so "../weather"
rendered the config form for "weather". Nothing escaped the plugins
directory -- the relative_to guards held -- but the handler answered a
request nobody made, and validating one string while the filesystem sees
another is the shape both live traversals earlier in this branch had.

Same treatment as the rest: safe_path_component rejects rather than
truncates, resolve_under returns the path it checked, and the call sites
use what those return. The three handlers that had hand-rolled
resolve-and-relative_to blocks lose about twenty lines to the shared one.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* docs(web): say what the plugin web_ui iframe actually is

The docstring claimed the fragment runs "in a sandboxed iframe". The
iframe in plugin_config.html carries no sandbox attribute, so the
fragment runs with the interface's own origin. That is fine -- the file
belongs to an installed plugin, and an installed plugin already runs
Python on the device, so the trust boundary is install rather than this
route -- but a comment promising containment that is not there is worse
than no comment. This is the context for the py/reflective-xss alert on
this handler.

Also drops the now-unused os/os.path imports.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(web): inline url-input's scheme guard at the previewLink.href sink

CodeQL flagged this line as a new high-severity js/xss-through-dom alert
on this PR even though it is already covered by SCRIPTABLE_SCHEMES: the
guard reached the sink through safeHref -> isValidUrl, two function calls
away, which its DOM-based-XSS sanitizer recognition does not trace.

Behavior is unchanged -- same scheme check, same SCRIPTABLE_SCHEMES list,
same allowedProtocols gate -- just inlined directly above the
previewLink.href assignment it guards, so the barrier is visible in the
same scope as the sink.

Added a regression test that runs the shipped onInput handler (not just
the extracted helpers) against a mocked DOM, so a future change that
reintroduces an unguarded previewLink.href assignment fails here.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(security): address CodeRabbit findings on the CodeQL triage PR

- src/wifi_manager.py: reject non-ASCII WPA-PSK passphrases before any
  credential-saving or connect flow runs. NetworkManager only accepts
  printable ASCII passphrases (or a 64-char hex key); a non-ASCII value
  was previously saved/attempted before nmcli itself rejected it.

- web_interface/blueprints/api_v3/config.py: fail closed when the
  plugin config schema path can't be resolved under the plugins
  directory (e.g. a symlinked plugin dir). Previously this fell
  through with secret_fields left empty, so submitted credentials for
  that plugin were saved as ordinary, unencrypted configuration.

- web_interface/static/v3/js/widgets/plugin-file-manager.js: stop
  splicing the JSON day/column key into an inline oninput="..." handler
  string. escHtml() escapes quotes for a normal HTML attribute, but the
  browser HTML-decodes the attribute before running it as script, which
  undoes that escaping and lets a crafted column name (e.g. from an
  uploaded JSON file) break out of the JS string and execute. Cell
  edits now travel through data-day/data-col attributes read by one
  delegated 'input' listener instead.

  While in this file: fixed 6 pre-existing missing-')' typos on
  multi-line safeSetHTML(...) calls (already flagged by Biome in this
  PR's own CodeRabbit run as syntax errors blocking its lint pass).
  These predate this PR (present on main too) but made the whole file
  fail to parse in any JS engine, which is a bigger problem than the
  XSS finding itself and directly touches the same lines.

Added/extended regression tests for each fix; full suites pass
(pytest: 4580 passed, 62 skipped; JS: 84 assertions).

ChuckandClaude Opus 5 bdb9a94033 refactor(api-v3): split the 10,469-line blueprint into a package (#553)
* refactor(api-v3): split the 10,469-line blueprint into a package

web_interface/blueprints/api_v3.py held 111 routes, 56 helpers and 181
functions in one module -- 9% of the core by line count and three times the
next largest file. It becomes a package of nine route modules grouped by path
segment, plus __init__.py for the shared imports, constants, Blueprint and
helpers.

Every route module decorates the SAME api_v3 Blueprint object, so endpoint
names stay api_v3.<function>, the URL map is unchanged and app.py is untouched.
Verified: 111 routes before, 111 after, byte-identical rules, endpoints and
methods, and every endpoint still on the one blueprint.

  plugins   3,867   config    1,178   starlark  692   system  619
  fonts       452   misc        398   wifi      361   display 326   backup 212
  __init__  1,787 (imports, constants, Blueprint, 56 helpers)

Two things the URL-map check could not catch, both found by running the suite:

1. PROJECT_ROOT = Path(__file__).parent.parent.parent. Moving the code one
   directory deeper made that resolve to web_interface/ instead of the project
   root. Nothing failed at import; it surfaced as ~110 tests failing with 404s
   and "installation script not found", because every path built from it was
   one level too shallow. Now parents[3], and test_api_v3_url_map.py asserts
   PROJECT_ROOT/run.py exists so the next move cannot repeat it.

2. Module-attribute patching. Tests do
   monkeypatch.setattr(api_v3_module, "_BACKUP_EXPORT_DIR", ...) and a route
   module that binds such a name by value never sees the patch. The shared code
   therefore stays in __init__.py rather than moving to a _common submodule --
   it has to live on the module the tests patch -- and the eleven names tests
   patch are read back through the package (_pkg.X) instead of bound by value.
   Those eleven were found by AST-scanning every setattr in the test tree, not
   by guessing; "time" is among them, used to drive a fake clock through the
   second-resolution credential-backup filenames.

Test changes are confined to what genuinely moved: patch targets that now name
the owning route module, imports of helpers, and six tests that scan the api_v3
source as a file and now read the package directory.

Full suite: 4,278 passed, 68 skipped, 0 failed.

* fix(api-v3): address CodeRabbit findings from the blueprint-split review

Fixes to the api_v3 package split (PR #553), one per finding verified
against the actual code:

- __init__.py: _redact_credentials only blanked scalar values under a
  credential-named key; a bare list of secrets under such a key (e.g.
  tokens: ["a", "b"]) passed through untouched, since the list branch
  recursed with no memory that its key looked like a credential. Nested
  dicts still walk normally (a documented, tested behaviour -- a container
  like secrets: {api_key: ..., note: ...} is a section name, not a value to
  blank outright), but any value reached under a credential-shaped key is
  now actually blanked.

- __init__.py: the OAuth helper script's raw stderr/stdout went to
  logger.error unredacted (CWE-532) right next to a comment claiming this
  was deliberate; the HTTP response already used the existing redact_text
  helper. Routed the log line through the same helper.

- __init__.py / starlark.py: the standalone Starlark manifest fallback
  (used when the plugin instance isn't loaded) read-modified-wrote
  manifest.json with no lock, unlike StarlarkAppsPlugin._update_manifest_safe
  (plugin-repos/starlark-apps/manager.py), which already holds an flock for
  the same file when the plugin is loaded. Added _starlark_manifest_lock,
  mirroring that pattern, and wrapped every standalone read-modify-write
  call site in it. The app-config update route also wrote config.json and
  the manifest as two separate, non-transactional writes (a second,
  distinct finding at the same call site); config.json is now rolled back
  if the manifest write that follows it fails.

- backup.py: restore options used bare bool() on values from the request,
  so {"restore_secrets": "false"} restored secrets anyway (bool("false") is
  True). Switched to the existing _coerce_to_bool helper already used for
  this exact purpose elsewhere in the package.

- config.py: an automated import-rewrite mangled four user-facing
  validation strings and their neighbouring comments -- "Invalid start
  time" had become "Invalid start _pkg.time" (and likewise for "end time")
  in both the schedule and dim-schedule per-day validation paths.

- display.py: `import _pkg.time as time_module` -- _pkg is a local alias
  for the package, not a real importable module, so this raised
  ModuleNotFoundError whenever a caller restarted an already-running
  display service via /display/on-demand/start, after the on-demand
  request was already written to cache. Fixed to `import time`. Audited
  the rest of the package for the same `_pkg.<module>` import mistake;
  every other `_pkg.` reference is a legitimate attribute read-through
  (`_pkg.time.time()`, `_pkg._get_starlark_plugin()`, ...), not a broken
  import statement.

- fonts.py: validate_file_upload's max_size_mb parameter is silently
  unused by that helper (it only checks filename/extension) -- the font
  upload route saved arbitrarily large files as a result. Added the same
  seek-and-check pattern already used for the sibling .star upload.

- wifi.py: two ad hoc, inconsistent bool coercions. POST
  /wifi/ap/auto-enable used bare bool(), so a JSON string "false" enabled
  it. POST /wifi/radio's enabled/force parsing recognized real bool and
  some strings but not int 1/0 (1 is True is False in Python). Factored one
  small _parse_bool_ish helper local to this file and used it at all three
  sites.

Not changed: the "unknown/misspelled restore option keys default to True"
half of the backup.py finding -- the file's own comment documents that a
missing key deliberately means "restore everything," matching the
already-existing JSON-parse-failure guard a few lines above it; only the
bool-coercion defect was a real bug.

Added or extended regression tests for every fix, following each area's
existing test conventions. Full suite: 4328 passed, 62 skipped, 2 failed
on both this branch and origin/main (missing tzdata package breaks two
timezone-alias tests in test_onboarding_checklist.py, unrelated to this
change) -- no new failures.

* fix(api-v3): reject unknown restore option keys

CodeRabbit's review of the blueprint split (#553) asked that
POST /backup/restore reject option keys outside RestoreOptions'
known set. The follow-up commit fixed the bool("false")-is-True
bug with _coerce_to_bool but never added the key check: a typo'd
or renamed key (e.g. "restoreSecrets") is silently ignored by
opts_dict.get(key, True), so the flag stays at its True default
and secrets get restored despite the caller's request saying
otherwise -- with no indication anything was wrong.

* fix(api-v3): address CodeRabbit findings on the blueprint split

- _redact_credentials: blank scalar descendants of objects reached
  through a credential-owned list (e.g. tokens: [{"value": "secret"}])
  regardless of field name -- the existing name-based walk only
  protected direct dict values under a credential key, not list items.
- wifi.py: reject enabled/force/auto_enable_ap_mode values
  _parse_bool_ish can't recognize (400) instead of silently treating
  them as False, which could disable Wi-Fi or the radio itself.
- Starlark manifest locking: lock a stable manifest.json.lock sidecar
  instead of manifest.json itself, in both the standalone route path
  (_starlark_manifest_lock) and the plugin path
  (StarlarkAppsPlugin._save_manifest / _update_manifest_safe).
  manifest.json is replaced by an atomic rename on every write, which
  swaps in a fresh inode; a lock held on the old inode does not
  exclude a second locker that opens the path afresh right after the
  rename and gets the new inode, so two writers could race despite
  each holding "a lock". A sidecar that no write ever touches always
  resolves to the same inode for every locker.

Skipped as stale: the "serialize the complete manifest
read-modify-write" finding at api_v3/__init__.py -- every standalone
handler that calls _write_starlark_manifest is already wrapped in
_starlark_manifest_lock() on this branch.

* fix(api-v3): re-check reconciliation findings by the reconciler's own rules

Both CodeRabbit findings on the merge commit, verified against the code first.

Major, plugins.py: the stale-findings filter derived its own notion of "in
config" and "on disk", and both were looser than the reconciliation module's.
set(load_config()) also contains system keys, the secrets-file keys load_config()
merges in, and non-dict values; and any directory holding a manifest.json
counted as installed even when that manifest does not parse. Either looseness
clears a finding that is still true -- and a secrets key read as a plugin is the
precise bug the filter exists to stop reporting, so reintroducing that asymmetry
while re-checking was the wrong way round.

The two extractions now live in state_reconciliation.py as config_plugin_ids()
and disk_plugin_ids(), with ignored_config_keys() and secrets_top_level_keys()
alongside. _get_config_state() and _get_disk_state() use them too, so there is
one definition rather than two that can drift. _get_disk_state() re-reads each
manifest for version/name after taking membership from the shared extractor;
that costs one extra small read per plugin on a path that runs once per boot.

Minor, the new test: the fixture assigned api_v3.config_manager and
api_v3.plugin_manager directly. Those live on a module-level blueprint
singleton, so the mocks leaked into every later test that imports api_v3 --
pointing at a tmp_path already deleted. Both now go through monkeypatch.setattr,
which restores them. This is the same pollution class that made an earlier test
in this session break seven unrelated ones, so it is worth getting right.

Five cases added for the parity itself: a secrets key, a system key and a
non-dict value must not clear an "installed but missing from config" finding,
and neither an unparseable manifest nor a .standalone-backup- directory may
count as installed. All five fail against the looser version.

Linux CI on the preceding commit: Core unit tests, plugin harness, CodeQL and
CodeRabbit all pass. Codacy reads action_required on every commit of this
branch including the first, so it is pre-existing and not from this work.

ChuckandClaude Opus 5 39f27d285d fix(plugins): stop reconciliation inventing plugins and telling users to delete real config (#557)
On a device running four installed, configured, working plugins, the overview
banner read:

  Stale plugin config entries found: football-scoreboard, odds-ticker, data,
  ledmatrix-weather, starlark-apps. Remove them from config.json or reinstall
  via the Plugin Store.

Every claim in that sentence was wrong, and following its advice would have
deleted 4.9KB of working league settings. Four separate defects combined.

1. Secrets keys became phantom plugins. load_config() merges
   config_secrets.json into the config it returns, and the ignore list named
   only 'github' and 'youtube'. A 'data' key in that file therefore read as a
   plugin id and was reported as "in config but not on disk" forever. Read the
   secrets file's own top-level keys instead of hardcoding two of them.

2. The auto-fix clobbered real config. The handler for "on disk but not in
   config" assigned `config[plugin_id] = {'enabled': False}` unconditionally,
   so whenever detection was wrong it replaced a plugin's entire configuration
   with a stub. On the reported device it only failed to do so because the
   write hit EACCES. Now it refuses to overwrite an entry that already exists.

3. The banner gave backwards advice. plugin_missing_in_config ("on disk, not in
   config") and plugin_missing_on_disk ("in config, not on disk") are opposite
   problems, and both were rendered as "stale config entries ... remove them
   from config.json" -- which is correct for the second and destructive for the
   first. They are now reported separately, each with the advice that fits.

4. A stale verdict was served indefinitely. The result is a snapshot written
   once per run to a status file, and a run that fails to apply a fix also
   declares it will not retry. A condition that had since resolved kept being
   reported for hours. The status endpoint now re-checks stored findings
   against current state, dropping only what it can prove stale and keeping
   any kind it cannot re-verify.

The secrets-key lookup is deliberately fail-safe: an unreadable, absent,
malformed or non-path secrets location narrows the ignore set rather than
raising. An earlier revision let TypeError escape, which the broad handler in
_get_config_state() swallowed as "Error reading config state" -- emptying the
config state and making every downstream detection wrong. The existing
reconciliation tests caught it; there is now a regression test for it too.

Each has exactly one occurrence across both repositories -- its own

A fourth candidate was dropped after checking: _unshare_element_fonts in
src/common/sports_shared.py looked unreferenced, but eight scoreboard plugins
call SportsCore._unshare_element_fonts directly from their
test_element_text_colors.py, plus their own copies at runtime. It is live API.
The earlier reading came from a plugins checkout 84 commits behind main, which
is a good argument for re-verifying this kind of claim against a fresh tree
rather than trusting an earlier scan.

ChuckandClaude Opus 5 577f5501a6 perf(plugins): stop re-deriving a display() signature the caller already cached (#549)
display_controller resolves once, and caches, whether a plugin's display()
takes a display_mode keyword -- self._plugin_accepts_display_mode, populated
right before the dispatch. It then handed the executor a
types.SimpleNamespace wrapping a closure, and execute_display() ran
inspect.signature() on that to work out the same thing.

Because the SimpleNamespace is rebuilt per call, the callable was new every
time, so nothing inside the executor could ever cache it either. Measured at
~39us per dispatch on a Pi 4, for a value the caller had a line earlier.

execute_display() now takes accepts_display_mode, falling back to inspecting
only when a caller does not pass it, so existing callers are unaffected.

Also documents two things that read as bugs and are not:

- execute_with_timeout()'s timeout is advisory. Nothing cancels the thread --
  Python cannot -- so on expiry the operation runs to completion in the
  background and only the caller gives up. A permanently hung plugin leaks a
  daemon thread per attempt. This is why callers holding a lock across the
  call must release it from inside the wrapped callable, as run()'s
  _release_display_lock already does.

- Only the first display() of each mode goes through the executor; the
  per-frame loops call display() directly. That is deliberate: a thread per
  frame would cost more than an advisory timeout buys. Both loops now say so,
  so the asymmetry does not read as an oversight.

ChuckandClaude Opus 5 ad5bc4b819 perf(sports): LRU-bound the decoded logo cache (#559)
SportsCore._logo_cache was a plain dict keyed by team abbreviation with no
eviction. Its entries are not file bytes but decoded RGBA thumbnails sized to
display*1.5 -- roughly 36KB on a 256x64 panel, more for wide wordmarks -- and
assets/sports/ncaa_logos ships 307 of them. A plugin that walked a full league
held the whole league resident: about 11-18MB per manager instance, and a league
runs three (live/recent/upcoming) that each keep their own cache, so the same
logos were duplicated across them.

On the 1GB Pi 3B+ this was measured on, one board was sitting at 439MB resident
with ~290MB available, so tens of megabytes of duplicated league logos is real
money. Bounded to 64 entries, which holds a full "other games" cycle (on the
order of 20 games, 40 teams) without thrashing while capping the cache well
below a 307-team league.

Eviction is LRU rather than clear-when-full, using the OrderedDict/popitem
pattern the neighbouring caches in this codebase already use (_IMAGE_CACHE_MAX,
_FIT_CACHE_MAX, _TEXT_WIDTH_CACHE_MAX). That ordering matters: the logos on
screen right now are precisely the ones that must not be discarded, so a cache
hit moves the entry to the end.

ChuckandClaude Sonnet 5 fb3b293ace fix(plugins): let a plugin ask to be polled faster while it has live content (#555)
* fix(plugins): let a plugin ask to be polled faster while it has live content

Reported: "the football plugin with live games only updates the live game in
progress if I restart the display."

The data path was never the problem. NFLLiveManager fetches ESPN with no cache,
SportsLive.update() refreshes current_game in place when the game IDs are
unchanged, and the scorebug redraws from the game dict every frame -- which is
why the reporter's logs look healthy.

The problem is cadence. _get_plugin_update_interval() read only the manifest's
static update_interval, football's manifest pins that to 60, and the plugin's
own live_update_interval (15s) was invisible to the scheduler. Measured on a rig
during the fourth quarter of the game in the report:

    23:21:49  23:22:50  23:23:50  23:24:50  23:25:50   <- exactly 60s apart

A clock and score up to a minute stale during a two-minute drill reads as a
frozen panel, and a restart is the one moment it is ever current.

A single static number cannot say "every 15 seconds while a game is on, every 15
minutes in July", and only the plugin knows which is true. get_update_interval()
lets it say so per tick; returning None means "no opinion" and the existing
manifest/config resolution applies, so every plugin that predates this is
unaffected.

Requests are clamped to MIN_DYNAMIC_UPDATE_INTERVAL (5s): a plugin returning 0
would otherwise be re-entered on every tick of the render loop, busy-waiting
against its own API. A hook that raises or returns a non-number is ignored
rather than propagated -- a scheduler that fails on one plugin's bug stops
updating all the others.

Deliberately NOT changed: the manifest still beats config in the static path.
That looked like the obvious fix -- user config being silently ignored -- until
checking a real rig, where football and baseball both carry update_interval 3600
in config against a manifest 60, and weather 1800 against 60. Those values are
stale precisely because nothing has been honouring them; making config win would
have slowed three plugins by 60x, turning a one-minute lag into an hour. The
dynamic hook makes the flip unnecessary. There is a test pinning the current
precedence with that reasoning attached.

* test(plugins): drive the real scheduler, not just the interval resolver

test_plugin_dynamic_update_interval.py asserts that
_get_plugin_update_interval() returns the number the plugin asked for. That is
not the same claim as "the plugin gets updated more often", and the gap between
those two is exactly where the original bug lived: the plugin knew it wanted
15s, said so in live_update_interval, and nothing downstream acted on it.

So this ticks the real run_scheduled_updates() through a simulated hour and
counts dispatches. Against pre-fix core it reports "10 updates in 10 minutes of
a live game" -- the 60s manifest cadence, matching what was measured on a rig
during the reported game. Against the fix it reports ~40.

Also pins the regression that would be worse than the bug: an idle hour must
still be ~60 updates, not 240. Asking for the live interval year-round would
poll ESPN four times a minute all summer.

Scope note, since it is easy to over-read this fix: the *switch* display path
already refreshed the manager immediately before drawing, via
_try_manager_display() -> _ensure_manager_updated(), which honours the manager's
own 15s interval. So a switch-mode card was already <=15s stale at draw time
before this change. What this fixes is the background cadence, which is what
live-priority detection, Vegas content and scroll preparation all read.

get_update_interval() ran bool through float() (bool is an int subclass,

cases landed on the MIN_DYNAMIC_UPDATE_INTERVAL floor by coincidence
instead of falling back to the static/manifest interval as invalid

ChuckandClaude Opus 5 28bc79566f fix(logo): remember a missing logo instead of re-warning every rotation (#548)
* fix(logo): remember a missing logo instead of re-warning every rotation

load_logo() stat'd the path and logged a WARNING on every call, and the
positive cache never covered it because a miss returns None and caches
nothing. A file that is simply not there therefore produced one warning per
rotation for as long as the process ran -- measured on a live rig at 114 lines
in 24 hours for a single missing ticker icon, for a file nobody was going to
add.

Misses are now remembered for 10 minutes: warn once, then return None without
touching the disk. Bounded rather than permanent because logo_downloader
writes logos at runtime, so a file that appears later must still be picked up
without a restart. Downloads through load_logo_with_download() clear the entry
outright -- load_logo() consults the miss record before it stats the disk, so
without that a freshly downloaded logo would stay invisible for the whole
window.

This is in the core rather than in ledmatrix-stocks, where it was found, so
every plugin that goes through LogoHelper gets it.

_cache_order stays a list. Swapping the pair for an OrderedDict would shave an
O(n) scan per cache hit, but n is capped at cache_size (100 by default) and
test_logo_helper.py pins the current structure; not worth the churn.

* fix(logo): make the miss TTL longer than the rotation it is meant to outlast

Deployed the previous commit to a live rig and measured it: no change at all.
"Logo not found for VOO" stayed at ~6 lines an hour, exactly the baseline.

The TTL was 600s and the display rotation is ~618s, so every recheck expired
just as the plugin came round again and the negative cache never once got to
suppress a warning. The fix was correct in shape and useless in practice,
which only measuring on the rig would show.

An hour instead. That is safe because the TTL is not the main way an entry
clears: load_logo_with_download() drops it the moment a download succeeds and
clear_cache() drops all of them. The TTL only covers a file that appeared some
other way -- someone copying one in by hand -- and waiting up to an hour for
that, or restarting, is a fair trade for not re-warning about a file nobody is
going to add.

The general lesson is in the comment: a TTL has to be long relative to the loop
that does the asking, not merely "a while".

ChuckandClaude Opus 5 12f3790994 fix(install): render the systemd units from their templates, not from heredocs (#547)
* fix(install): render the systemd units from their templates, not from heredocs

The installers carried their own inline copies of units that also exist as
templates under systemd/, and the copies drifted.

install_service.sh renders ledmatrix.service from the template correctly, then
wrote ledmatrix-web.service from a heredoc that predated it -- missing
Wants=network-online.target, RestartSec=10, SyslogIdentifier, CacheDirectory,
CacheDirectoryMode and Environment=USE_THREADING=1. install_web_service.sh had
a third copy, and install_wifi_monitor.sh a fourth, that one already differing
from its template (syslog where the template says journal).

startup_validator.py compares the installed unit against the template, so a
rig installed this way warned on every boot -- and the remedy the warning
names, "re-run scripts/install/install_service.sh", reinstalled the same stale
copy. The warning could never clear. Reproduced on a live rig running exactly
that unit.

All three installers now render systemd/*.service through the same placeholder
substitution. The template gains a __USER__ placeholder rather than hardcoding
User=root, because the web interface runs as whoever installed it.

That last point was a second, independent cause of a permanent warning: the
validator substituted a fixed "root", so any non-root install reported drift
forever. It now reads User= from the installed unit -- an install-time
decision, not something the template dictates -- and compares everything else
strictly. first_time_install.sh already reads the installed User= the same way.

Tests cover a non-root web unit not warning, a genuinely changed directive in
that unit still warning, the User= fallback, and a grep-based guard that no
installer under scripts/install/ contains an inline unit body. That guard is
what found the install_wifi_monitor.sh copy.

* fix(install): escape sed replacements, use mktemp, and make render failures fatal

Address CodeRabbit findings on install_service.sh, install_web_service.sh and
install_wifi_monitor.sh:

- Values interpolated into each script's sed expression (project root path,
  username) were not escaped, so a value containing &, \ or the | delimiter
  would corrupt the rendered systemd unit. Add a shared
  sed_escape_replacement() helper in the new scripts/install/lib_systemd_render.sh
  (sourced by all three scripts) and apply it to every sed replacement.
- install_service.sh rendered the main and web units to the predictable path
  /tmp/ledmatrix.service.tmp before installing them -- a symlink/TOCTOU race
  (CWE-377). Use mktemp for both, with a trap to clean up on exit.
- install_service.sh treated a missing template as a mere warning and then
  checked only whether a unit already existed at the destination before
  enabling/starting it, so a render failure could silently fall back to
  enabling a stale, previously-installed unit. Both unit blocks now exit
  non-zero on a missing template or a failed render.

Also rename the ambiguous loop variable `l` to `line` in
test/test_systemd_unit_drift.py (Ruff E741); ruff isn't wired into any CI
workflow in this repo today, so this isn't currently CI-blocking, but the
rename is trivial and correct regardless.

CodeRabbit asked for regression coverage using a project path containing an
ampersand; the earlier commits on this branch already fixed the escaping,
mktemp usage, and enable/start-on-fatal-render-failure findings, and the
l->line rename was already applied -- this closes the one remaining gap.

ChuckandClaude Opus 5 a29c84208e fix(scroll): advance whole pixels per frame, not per wall-clock second (#545)
* fix(scroll): advance whole pixels per frame, not per wall-clock second

Smooth motion is not a frame-rate property, and measuring it as one is why
this survived three rounds of fixes. odds-ticker's frame timing is excellent
-- 100.0 fps, 10.00ms median, 0% stalls, worst in-scroll frame 19.95ms -- and
it still visibly stuttered.

What the eye judges is whether the strip advances the same number of whole
pixels on every presented frame. update_scroll_position derived position from
scroll_speed * delta_time and get_visible_portion truncated it with int(), so
jitter in delta_time decided which side of a pixel boundary the position
landed on. The live windows show why that matters: a rock-steady 100.0 fps
whose individual frames still range 5.6ms to 15.2ms, which at 100 px/s is
0.57px to 1.44px of movement.

Run the measured frame times through the real helper and 5.8% of frames
advance 0 or 2 pixels instead of 1 -- about six hitches a second. A frame that
moves nothing followed by one that jumps two is exactly what micro-stutter
looks like.

It is worst at a crisp speed, which is the part that stings: at 100 px/s on a
100Hz panel the accumulator sits exactly on integer boundaries, so
sub-millisecond jitter flips it either way and the motion beats at around
50Hz. Snapping to the crisp ladder fixes the average and the wall clock then
throws away the per-frame uniformity the ladder was bought for.

So when scroll_config snaps to a crisp speed it now also puts the helper in
fixed-step mode: each presented frame advances exactly pixels_per_frame and no
clock is consulted. 100% of frames move by the same amount, whatever the
jitter.

This is only correct because SwapOnVSync blocks until the panel has taken the
frame, which makes the frame count a truer clock than time.time(). Before the
swap was locked to vsync it would have run at whatever speed the loop spun at.
Related: frame-based mode used to step discretely and was converted to
elapsed-time accumulation earlier in this series, because its threshold
comparison flipped on jitter. That was right for the code as it stood -- but
it treated the symptom, replacing a broken discrete step with a smooth-looking
accumulator instead of asking why a wall clock was involved at all.

Non-crisp speeds keep pacing off time, and set_scroll_speed() clears the fixed
step so a legacy caller changing speed is not silently ignored.

Trade-off worth naming: speed is now tied to the presentation rate rather than
to real time. If the loop cannot keep up with the panel the scroll runs slow
rather than jumping to catch up. That is the better failure -- uniform motion
at a slightly wrong speed beats correct average speed with a hitch six times a
second -- and a loop that cannot hit the resolved rate is a measurement
problem for the crisp ladder, not something to paper over with uneven steps.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test(scroll): make the time-based pin actually pin something

Review caught that test_time_based_stepping_is_what_it_replaces could pass
against perfectly uniform motion, and it was right.

update_scroll_position sets last_update_time on its way through, so the very
first call sees a delta_time of zero and moves nothing in time-based mode.
_advances counted that synthetic frame, which put a guaranteed zero in every
histogram -- enough on its own to satisfy "uneven > 0". The test asserting the
defect exists would have passed after the defect was gone.

The first call is now primed and discarded, and the assertion is a proportion
rather than "more than zero": against these frame times the old path misses
roughly one frame in twenty, so 1% is well below the real rate and far above
anything a stray frame could produce.

Re-measured with the artefact removed, the numbers in the PR description are
unchanged: 5.85% of frames uneven before (114 zero-advance and 120 double
frames in 4000), 0.00% after.

Also fills in the docstrings the review flagged: everything in the new test
file, plus three pre-existing one-liners in scroll_config that the diff
touched.

ChuckandClaude Opus 5 f8e2e89edc refactor(sports): put the scoreboards on the shared scroll resolver (#542)
* refactor(sports): put the scoreboards on the shared scroll resolver

Eight sports scoreboards -- afl, baseball, basketball, football, hockey,
lacrosse, nrl, soccer -- scrolled through this module's own pacing while the
other eleven scrolling plugins went through src/common/scroll_config. Two
implementations of the same job, and this one was on the losing side of every
difference.

It never called set_scrolling_state. Two consequences, both of which this
release's work was about:

- The frame hold is applied through that call, so a speed the crisp ladder
  could render in whole pixels still presented a new frame every refresh.
- Core only runs deferred updates while nothing is scrolling. Believing
  nothing was, it ran blocking work in the middle of these scrolls.

The default is non-crisp today: scroll_speed 50.0 with scroll_delay 0.01 is
50 px/s, which on a 100Hz panel is half a pixel per refresh. That cannot
render as motion -- it alternates 0px and 1px steps and judders at a 50Hz
beat, on every scoreboard, out of the box. Resolved through the ladder it
stays 50 px/s and holds each frame for two refreshes: same speed, whole-pixel
motion.

The stepping disagreement that used to justify a separate module is gone.
scroll_config avoided frame-based mode because it stepped on a wall clock at
1/scroll_delay with scroll_delay set to the frame period, so the decision sat
on its own threshold and flipped on sub-millisecond jitter. That branch now
accumulates elapsed time, identical arithmetic to the time-based one, so the
two differ only in the units the speed arrives in.

What is NOT shared, and must not be: the two modules read identically-named
keys with different meanings. Here scroll_speed is px/SECOND and scroll_delay
only converts to px/frame; in scroll_config scroll_speed is px per STEP, so
px/s is speed/delay. Passing this module's settings dict to the resolver turns
50 px/s into 5000, clamped to 500 -- a tenfold speed-up everywhere. So
_get_scroll_settings keeps sole ownership of reading sports config, including
the league merging, and hands the resolver a plain px/s. A test pins that
specific number, because it is the mistake the refactor invites.

MIN/MAX_PIXELS_PER_FRAME are gone; the resolver bounds speed and the helper
clamps FPS. _resolve_target_fps stays, re-purposed: under the old model that
key was the rate frames were presented at, so it is the faithful translation
into the refresh the ladder is computed against, used when no hardware
refresh is configured.

Speed changes for panels that are not 100Hz: 50 px/s becomes 60 at 60Hz
(+20%) and 48 at 120Hz (-4%). At 100Hz it is unchanged.

* fix(display): drop the frame hold when a scroll times out, not just when it says so

set_scrolling_state(False) clears the hold. The other way a scroll ends is
is_currently_scrolling() deciding, after scroll_inactivity_threshold of
silence, that it is over -- which is what happens when the rotation moves on
mid-scroll or a plugin is torn down. That path cleared the flag and kept the
hold, so every later plugin, scrolling or static, was presented at refresh/N
by whoever scrolled last, until something called the explicit stop.

The method's own docstring already states the rule this breaks: the hold "must
not outlive the scroll that asked for it". The timeout was the exception it
did not cover.

Pre-existing, but reachable by three plugins before and eleven after the
sports scoreboards moved onto the shared resolver, so it belongs with that
change. The test ages the activity timestamp past the threshold rather than
sleeping.

Also adds scripts/sports_scroll_check.py. The sports scroll path is per-league
opt-in, so a rig showing static game cards never constructs a
SportsScrollDisplay and none of its pacing can be observed from a normal run
-- which is exactly what happened when this change was first put on hardware:
26 minutes, zero sports scroll lines. The script drives the path directly with
synthetic games and asserts the three things the resolver is meant to buy: the
speed lands on whole pixels, the hold is published, and it is released after.
It never starts or stops the display service, matching scroll_speeds.py, so a
crash here cannot leave the panel dark.

* fix(scripts): refuse to grab the panel while the display service has it

The module docstring already said to stop ledmatrix first. Nothing enforced
it, and running the script against a live service is not a harmless mistake:
rpi-rgb-led-matrix configures GPIO directions and the hardware PWM inside
RGBMatrix(), and when the root check fails it calls exit() from C with no
cleanup. The service keeps rendering and swapping onto pins that have been
reconfigured underneath it, so the panel goes black while every diagnostic
says the display is healthy -- fresh framebuffer, every pixel lit, "RGB Matrix
initialized successfully", nothing in the log. A restart fixes it, once you
work out that is what happened.

Found the hard way: this is what took the panel down on the test rig, not the
change the script was written to verify.

--fallback skips the check, since it never opens the matrix. --force is there
for anyone who means it.

* chore(scripts): annotate the subprocess call the way this repo already does

Codacy fails a PR on one new issue, and bandit B404 fires on any subprocess
import. scripts/run_plugin_tests.py carries the same suppression with the same
justification -- list-form argv, no shell -- so this follows it rather than
inventing a second convention.

ChuckandClaude Opus 5 968b953a51 fix(display): pin one text layout engine, and give the 5x7 BDF face a size (#539)
* fix(display): pin one text layout engine, and give the 5x7 face a size

Two ways a font could render differently on two machines running the same
code, both found while diagnosing four plugins whose golden images passed on
the machine that generated them and failed everywhere else.

**Layout engine.** `ImageFont.truetype` picks its engine at load time: Raqm
where the host Pillow was built with libraqm, Basic otherwise. The two round
fractional glyph advances differently. `PressStart2P-Regular.ttf` at 8px has
whole-pixel advances, so they agree — which is why most of the fleet matched
everywhere and hid this. `4x6-font.ttf` at 6px does not: glyph positions drift
cumulatively along a run, and the four plugins that draw body text in it
(geochron, of-the-day, christmas-countdown, ledmatrix-weather's almanac) are
exactly the four whose goldens travelled badly.

Every core font load now goes through `src/common/font_layout.load_truetype`,
which pins the Basic engine, so a render depends on the font file and the size
and nothing else. Basic gives up complex-script shaping and kerning pairs;
neither applies to bitmap-grid faces on an LED panel. Output is unchanged on a
host without libraqm.

**Zero font height.** `DisplayManager` built the 5x7 BDF face with
`freetype.Face(path)` and never called `set_char_size`, so `face.size.height`
stayed 0 and `get_font_height()` returned 0 for it — callers stacking rows by
`prev_y + prev_height + gap` drew two lines on top of each other. The
start-up line `Calendar font size: 0 pixels` has been printing the symptom all
along. `font_manager._load_bdf_font` already called `set_char_size`, so
whether measurement worked depended on which path loaded the face.

`DisplayManager` now sets it too, and `get_font_height()` falls back to the
strike the file declares rather than returning a zero line height.

* fix(display): give the startup banner a rung that fits a full address at 64px

CI caught what pinning the layout engine exposed rather than caused.
`_fitting_font` walks PressStart2P then 4x6 at 6px, and "255.255.255.255" --
the widest thing the startup banner ever shows -- measures 66px at 4x6/6px
against the 62 a 64x32 panel has to give. It used to squeak in only because
the measurement depended on which layout engine the host Pillow happened to
have; with the engine pinned it does not, so the rung the worst case actually
needs is now in the ladder instead of implied: 4x6 at 5px, which measures 51.

The fallback was wrong in the same place. When nothing in the ladder fit, it
returned `self.font` -- the *widest* option, and precisely how "Initializing"
came to run off the side of a 64px panel to begin with. It returns the
narrowest face that loaded now.

test/test_initializing_screen.py: 34 passed.

* fix(display): name the exceptions the BDF strike read can raise

Codacy flagged the try/except/pass. It was already narrow in intent -- a
malformed strike table on the measurement path must degrade to "size unknown"
rather than take the display down -- but a bare `except Exception: pass` says
neither of those things and hides a genuinely broken font behind a silent 8px
fallback. It now catches what reading `available_sizes` can actually raise and
logs which face failed.

* chore: drop logo PNGs the render harness downloaded into the worktree

These are fetched at runtime by the logo cache; they are not source, and they
rode in on a `git add -A` while I was running check_plugin.py against this
branch. Nothing in the change needs them.
